Garmin Fenix 6 vs Suunto 9 in-depth comparison – there’s a clear winner

Garmin Fenix 6 vs Suunto 9 in-depth comparison – there’s a clear winner

Suunto 9 and Garmin Fenix 6 are the top sports GPS watches currently. Both are well made and include more features than you probably know what to do with. But both are also very expensive. How do you know you get the right one?

I’ve been trying to find a good hiking watch for a long time. When Apple Watch 4 came out with its improved sensors, I wanted to see how well it would work as a GPS watch. The watch and software were leaps and bounds ahead of the competition, but it didn’t work well for what I needed it. The hiking view offered minimal useful info, not even altitude. The battery only lasted for a few hours of activity, making it less than ideal for long-distance hiking.

As I was giving up on the Apple Watch, Garmin launched a new GPS watch that looked promising: Garmin Instinct. It looked kind of dorky, like a 80s Casio, but the specs looked really promising. Long battery life, rugged, and tons of customizable data screens. Once I got over the lo-fi display, I really liked the watch. I could have all the data I needed right at my fingertips. But the watch had some issues. First, the GPS and heart rate sensors were not reliable. Second, the “military grade” construction wasn’t living up to it’s promise – the strap broke after only two months of light use.

Frustrated, I continued looking for a new watch. Essentially, my options were the Garmin Fenix 5 or the Suunto 9. After my problems with the previous Garmin, I decided to go with the Suunto. At almost 600 dollars, it was significantly more expensive than the Instinct. I hoped it could live up to my expectations.

The build qulity of the Suunto was amazing compared to the Instinct. The software looked beautiful. Although I ended up using the Suunto 9 for over seven months, there were several things that kept me from being completely satisfied with it. So when Garmin launched the Fenix 6, I decided to give it a try. The specs sounded exactly like what I was looking for.

Is the Fenix 6 better than the Suunto 9? Yes. So. Much. Better. Read my comparison below to see why I think the Fenix 6 blows the Suunto 9 out of the water.

Compared Fenix and Suunto models

In this post, I’m comparing the Suunto 9 Baro model with the Fenix 6 Pro.

There is a mindboggling array of different Fenix models, so I’ll try to point out if some of my comments aren’t applicable to a specific model.

I’m not going to spend time discussing the Suunto 9 base model without a barometer, as it’s not well suited for hiking.

Build quality, looks, and first impressions

The Suunto 9 is larger than the Garmin Fenix 6
Size comparison of the Suunto 9 and Fenix 6

The Suunto 9 is an impressive watch. It’s clearly well constructed out of quality materials. Everything feels solid and rugged. The buttons have a smooth action.

In contrast, the Fenix 6 feels a bit cheap and flimsy. Everything on the watch is functional, but looks have clearly been an afterthought. The buttons stick a bit and have an awkward click when you press them.

Winner: Suunto 9

Comfort and fit

The Suunto 9 is a massive watch, there’s no getting around that. It’s both wide and tall, which makes it awkward at times. It catches on sleeves and backpack straps. You need to wear it half-way up your arm for the heart rate sensor to get a decent contact with your skin.

The Fenix 6 is more slender. It comes in three sizes: 6S, 6, and 6X, in growing order. The 6X is closest in size to the Suunto 9.

The straps on the Fenix 6 are hinged instead of solid rubber, wich make for a more snug fit around your wrist. This means it’s able to get a good heart rate reading while you’re wearing your watch like a normal human being.

Winner: Fenix 6

Both watches come with LCD screens that are optimized for outdoor visibility and low battery consumption. They are nowhere as impressive as something like the Apple Watch, but then again they come with 10+ days of battery life instead of 1 day.

That said, the screen on the Fenix 6 is clearly better than the one on the Suunto 9. Its crisper and more legible without the backlight on. It looks like Garmin took the same high-contrast display they used on the Instinct and improved the resolution of it. The screen on the Suunto 9 is not as easy to read, especially in low light.

Suunto chose to put a touch screen on the Suunto 9, which I think was a bad call. It’s slow to respond, and makes the watch difficult to use when wet. Garmin decided wisely to go with a button-only user interface which works reliably in all conditions.

Winner: Fenix 6

Battery life

The Suunto 9 has an impressive battery life. With the longest tracking interval, it promises up to 120 hours of tracking time. It fills in the blanks between the points by using the compass and barometer, so you end up with surprisingly accurate results.

For most people, the almost 30 hours you get from with the best tracking accuracy is more than enough. It easily lasts two days of all-day thru-hiking.

The Fenix 6 has clearly borrowed the idea of battery mode options from Suunto. It too offers customizable modes that you can change during the activity if needed. You get 30+ hours of tracking with the GPS on best accuracy and heart rate monitoring turned on.

Both watches offer multiple days of heavy use tracking, so in my use they are more or less tied.

Winner: Suunto 9

Sensors and accuracy

The Suunto 9 watch has good GPS and decent altimeter accuracy. But the heart rate sensor is not very good. It works fine while you’re not working out, but once you use it for its intended use, things start to go bad. The only activity that worked well for me was running. Other activities, like hiking, cycling or strenght training would give me wildly inaccurate results.

Suunto recommends that you wear the watch two finger-widths above your wrist bone for best results. Having the watch that high up on the arm both feels weird, and is impractical as rides down when you start sweating – especially when riding a bike. It means that the Suunto 9 HR monitor is mostly useless while you’re working out.

The GPS accuracy on the Fenix 6 has been good based on my initial obsercations. It seems to handle even wooded areas with good accuracy. The altimeter automatically calibrates both based on GPS and the built in topographic maps (on Pro versions) during the activity, which has given me the most accurate altitude readings of any watch I’ve ever owned.

Equally, the Fenix 6 heart rate monitor has surprised me positively. I can wear the watch as normal, and it works reliably in every activity I’ve tried.

In addition to heart rate monitoring, the Fenix also measures pulse oxygen saturation. You can either measure manually, or turn on periodic measurements throughout the day for a small battery penalty. Knowing your blood oxygen saturation can be helpful in understanding how well adapted you are to altitude.

Edit October 2019: Garmin recently also enabled respiration rate tracking with a software update. It

Winner: Fenix 6.

Watch software

The interface on the Suunto 9 is very barebones. You have limited options when it comes to configuring data on the watch face or information you want to access in the menu. The menu is clunky and not very intuitive. Navigations, especially using the touch screen, are slow.

The Fenix 6 is almost the complete opposite. You can configure anything and everything on the watch. There are tons of watch face options, ways to configure widgets and data you want to have quick access to. The menus and widgets on the Fenix are much more responsive than on the Suunto, making it more enjoyable to use.

On the Suunto watch, you need to configure activity displays ahead of time on the phone app, whereas the Garmin lets you modify them right on the watch, even during an activity.

The activity screens on the Fenix are more customizable than on the Suunto. You have access to many more sources of data, and you can add as many or few dispays as you want.

The Fenix receives updates automatically to the device and updates itself, whereas the Suunto requires a computer connection.

Winner: Fenix 6.

Smartwatch and activity tracker functionality

Suunto 9 supports 24/7 heart rate monitoring, step count, calorie count, and showing notifications from mobile phones. It also tracks your sleep if you wear it over night (although you can only follow it on your watch).

The watch face on Suunto offers limited configurability. Depending on the selected watch face you can see steps, calories burned, and sunset/sunrise information. It can be hard to find a watch face that allows you to show all the info you want, with a look you want.

The Fenix 6 tracks and shows an incredible amount of data about yourself. You can get detailed stats on HR, pulse ox, stress level, respiration rate, and “body battery,” which is an overall number of how well rested you are.

The Fenix lets you drill down into the stats right on your watch, and gives even more detail in the app.

The Fenix can also show notifications from your phone, and has support for widgets that update from the internet – like weather info. I’ve especially found the weather data useful on my watch.

Winner: Fenix 6

Phone and computer software

Suunto has two apps for phones, an older Movescount app and a newer Suunto app. The Suunto app has a slick design, but lacks many (most) of the features in the older app. A lot of data are not available on the app. For instance, you get a sleep summary on the watch after each night, but on the phone you can only get information on how long you slept.

The connection between the Suunto app and the watch is flaky. You have to open the app to sync any activities, and often the app refuses to connect to the watch. Sometimes, it’s enough to force-quit the phone app. Other times, you need to go to the watch an turn airplane mode off and back on for it to start working.

Suunto has 3-4 different web sites that for some reason don’t share login details. You need to create several different logins and sometimes it’s really not obvious which one you should be logging in with.

The Garmin Connect app is clearly an engineer-designed app. It’s ugly, but it works and gives you access to more data and insights than you know what to do with. The app syncs activities almost instantaneously and connects to several third-party apps so you can get access to all your relevant fitness data in one place.

Both apps export activities to Strava which is a must-have.

Winner: Fenix 6.

User experience

Although this has mostly to do with software, which I covered above, I wanted to bring up the general user experience of the watch as a separate topic as I think this is where Suunto failed.

If I had to guess, I would say that the one single biggest difference between the two watches is that Garmin has listened to their users and built a watch that fulfills their needs while Suunto has designed a watch they themselves think is good.

A couple trivial, but telling examples:

When you travel, the Fenix updates its time and location info automatically when you get a cell signal and the app figures out where you are.

In contrast, with the Suunto watch, you have to first scroll through settings menus to find the right time zone, and then spend 5 minutes outside to get a GPS signal if you want to get location-specific data like sunrise and sunset times.

Speaking of sunsets: the Suunto has a watch face where you can see the sunset time. The problem is that once the sun goes down, it tells you when it will set tomorrow. If I’m sitting in a dark tent in the wilderness, I’m more interested in knowing when the sun goes up, than when it will set again tomorrow. Garmin has clearly listened to their users, as their watch face switches between sunrise and sunset times depending on which one is up next.

Another mind-boggling omission on the Suunto is that there’s no way of turning off the watch except to wait for the battery to run out. On the Fenix, it’s available as a menu option. This means that if you want to take off the Suunto, and don’t want your house to turn into an EDM club from the heart rate monitor’s green LEDs, you need to figure out how to turn off the 24/7 HR tracking instead.

Winner: Fenix 6.

The Fenix 6 is the clear winner for me. It has accurate sensors, a crisp screen, and is highly customizable. It comes with a reliable companion app on the phone that displays more stats about your body than you know what to do with.

The Suunto 9 is good-looking and well-constructed, but it’s let down by poor software. Both the watch software and the phone app are very barebones and lack seemingly obvious features. Suunto could narrow this race significantly by improving their software.

If you have any other questions, feel free to post them in the comments below and I’ll try to answer them.

  1. Wow, thanks a lot for your in-depth comparison, very usefull for me as it is time to choose my next mountaineering smart watch ?

    1. I’m glad you found it useful. I had such a hard time finding a watch I really liked that I wanted to try to help anyone else in the same situation.

  2. Impressive and detailed report! Thank you for sharing your insights. Definitely a big help for my next decision.

  3. I am Suunto traverse alpha user and decided to upgrade. I have really hard time what to pick 6x or suunto 9 titan. Do you notice any gps problems on garmin. Looking the forums it looks like 6 have a lot of sw and hardware problems. Thank you.

    1. I’ve been very happy with both the GPS performance and software on the Garmin.

      I did have some software issues, especially on the phone, with the Suunto. It would frequently require me to force quit the app or toggle airplane mode on/off to get connected again.

      1. Does garmin have an option to chnage gps sampling from 1 sec like suunto is doing with “best”, “ok”,”good”.?
        Looking 6x i can see 60h in gps mode. This is probably in 1sec interval? But do i have option to change it to something like suunto is having? I know there is ultra mode and expedition mode. But not interested in those.

        1. No, only ultra track. You can also turn off GLONASS and other watch features for extra battery life.

          I’ve only ever used mine in the normal mode, which has lasted 3-4 full days of backpacking. So I honestly haven’t even explored the other options.

  4. Hi Marcus. I have a Suunto 9 baro for 5 months and the reason i bought it instead of Phoenix 5 was the ability to see my HR in the water. Its very accurate. I have test it by counting my beats with the classic way (6”x 100) several times in the pool. I have also done an endurance test at a cardiology center last week and compared the watch’s indications with the computer’s. It was extremely accurate with a deviation of +- 2 pulses. It is true that the watch should be placed in the position suggested by SUUNTO otherwise Its all wrong. I had no problem at hiking or running although i’d like a screen with better contrast, too.

    1. Optical heart rate sensors can sometimes work very differently depending on the person. A big contributor to the Garmin working better for me is probably just that it fits better on my wrist.

  5. I find some of the verdicts here more as a matter of preference.

    Screen: of course Garmin is more readable but Suunto has sapphire screen which is known to have certain amount of glare and thus less readability. But many people, including myself, prefer sapphire for known reasons. Screen is also bigger (same as Garmin 6X), much more easier to read for a 50 yrs old dude as me

    Comfort and fit: I prefer much more Suunto. Example: when doing outdoor activity in winter and wearing gloves, I shall much more easily press buttons on my watch (Suunto 9B titanium) than on Garmin

    Last but not least: price Suunto 9baro vs Garmin 6X is tremedous. I chose Suunto exactly because it is not loaded with zillion features but has all the neccessary ones I need. Admittedly software is weak point but company is making strong progress.
    Disclaimer: I am just an ordinary athlete, have no stake at promoting neither brand

  6. Hi, thanks for the review. I have the Suunto baro 9 and agree with what you have said.
    It wasn’t until after I bought it that I realised it could not be turned off! Showing my age maybe but it never even occurred to me that an electronic device could not be turned off. I wanted to be able to turn it off for long periods on multiday hikes and then turn it on for navigation and route tracking in tricky conditions.
    The flickering green light that will not die causes my wife endless amusement – “your mistress wants you back” she says as it lights up the bedroom…
    Will probably try the Garmin next time, especially as Suunto is phasing out the ability to program waypoints in ahead of your trip through their software.

      1. Suunto will introduce waypoints beginning 2020.
        Not being able to turn off does not bother me as it has incredible amount of juice.
        Not using it for constant HR measurement so no comment in this department

  7. I expected the Garmin to be much better than the Suunto in terms of overall performance, but I believe the Suunto might be a better watch in terms of value. In SA the Suunto 9 is priced around 35% lower than the Garmin, key factor to consider..

    1. Yes. The price will, of course, be a big factor for most people. In addition to being cheaper to begin with, Suunto seems to have 20-40% discount campaigns on their watches a few times a year.

  8. Thanks a lot for your review. It gave me all the infos I was booking for.

  9. I’m very glad I found this review, but also bummed out, as I was planning to get the Suunto 9 baro. I really hope that Suunto puts a lot of effort into releasing an incredibly functional and well thought out Suunto 10. It should look like the Suunto 9 in terms of form factor (it is the best looking gps watch by far, IMO) but maybe with more actual screen and less bezel, have the same great battery life but with more user controlable modes, a better user interface (ditch the touch screen!), better maps, have the ability to play music and sync spotify playlists/podcasts like the forerunner, and they absolutely need to consolidate their apps and web pages into one functional, visually pleasing app that handles everything. If they did this, they could have the one end all be all smart gps watch. That is assuming Wahoo doesnt beat them to the punch…

  10. I brought suunto 9 titanium and was happy with it until I discovered it lacked Ant+ technology. It meant it wouldn’t connect with running or other activity machines.

    I liked the range of sports but disappointed by the lack of compatibility.

    I also worried about the magnetic charging cable losing its ability to connect.

    Good or bad the watch was stolen recently so I’m in the market for a new watch… larger the better but I’m put off by over supply of days in garmin and price vs. Lack of connectivity in the suunto.

  11. “app is clearly an engineer-designed app. It’s ugly, but it works” – you’ve made me laugh out loud, being a software engineer myself 🙂
    Thanks for the great review. I’m starting to look for a replacement for my old Ambit 3… Did you try following GPX track on these watches? How well does this work?

    1. Haha. I’m an software engineer too, so I know them when I see them ?

      I haven’t tried using the watch for GPX tracks. I use Gaia GPS and/or paper maps for primary navigation.

      I could see the watch being more useful for navigation on runs or when you’re not carrying anything else on you.

  12. Ive been a Garmin Fenix watch user. My thoughts with Garmin watch is that it’s performance is good only for a year. Watch failed even the basic functionality overtime. In my case after a year of using it not even in harshest use only as a daily time watch it didn’t charge anymore instead discharging when you charge it. Now how somebody claim it worth a price for durability. When it comes to service it sucked as well I contacted their customer care deemed more complicated than counting the sand on the beach. I was a member of a group GARMIN Fenix xx owner group. Damned I never thought the admin himself is an arrogant asshole paid bastard for covering up Garmin issues. When I opened up my case immediately I was suspended from making comments. Mind you, think before wasting money on useless things. By the way my unit is Fenix 5x and is still dead till now and just a year old from time of purchase

    1. That sucks. I had issues with an earlier Garmin Instinct. So far, things have been good with the Fenix with the exception of a short period of time where an iOS update broke the sync.

      I agree that it’s super frustrating if you buy something this expensive and the company doesn’t stand behind it and make sure it works.

    2. Did you contact Garmin customer service directly?, there customer service has always been amazing, I just sent them an email with pictures and details, My forerunner 235 has been replaced twice in the last 3/12 years, always got the replacement within about a week. MY FR235 doesn’t leave my wrist, unless charging. It must do about 5-6 hours of trail running a week plus downhill MTB and climbing. It takes a beating.
      My brother used my old 625, which I brought a few months after release, and it is now slow to pick up the GPS, but still tracks well once it has a signal.

    3. Shame you’ve had such an issue with your Fenix. I was actually looking for a comparison on the Suunto 9 Baro. I have an older X10 Military that I stopped using when the sync cable busted, then it became completely unusable after the strap went. Suunto doesn’t stock these parts, and they’re custom fit for the watch model, so it’s permanently unusable at this point.

      I replaced it with a Fenix 3 in 2015, and that watch been rock solid since the day I purchased it. It has some minor annoyances, mostly with having to wait for GPS fix at the start of an activity, but there are work arounds for it. The only features it lacks that I really look forward to are built-in health monitoring metrics, and maps.

      Only looking at a Suunto because they’ve offered a discount for the issues I’ve had with the X10, but it’s not a significant enough of one for me to seriously consider buying one, especially based on this review. Working with Suunto support has been extremely slow (I’m guessing due to time zone differences), and the compensation they’re offering doesn’t really give me the impression they stand fully behind their product. The X10 was every bit as expensive as the Suunto 9 Baro’s higher end models, and the discount they’re offering is extremely paltry compared to the total price of the two watches combined.

  13. Thanks for a thorough review. And reading peoples comments was very helpful too. Im looking to cash out on my first watch of this type and I’m leaning between these two. Wondering about serviceability though, I reckon you can swap the battery on them when the time comes. Do you happen to know how long the warranty is for them?

    1. I don’t know if you can change the battery, but I would assume so. The watch has a 1 year warranty, so it’s unlikely you’ll manage to wear out the battery that fast. I haven’t noticed any decline in battery life in the 6 months I’ve had mine

  14. Thanks for the comparison. Just bought the fenix 6 sapphire – looking forward to using it!

  15. Thanks for the awesome review!
    I received the gift of a Suunto X10 in Afghanistan in 2008 and the bezel cover broke literally on day one. I sent an email to Suunto explaining my situation and the issue. My team all had the same issue within days. One of our guys smashed his with the butt stock of his weapon in disgust. Suunto quickly responded via email and sent me (us) a replacement bezel cover to my Afghanistan remote APO (14 day turnaround) at no cost with instructions that worked very well until I unloaded the watch on eBay several years later. I really relied on that watch because I found that I could hop out of a vehicle and get a 10 digit grid faster and more accurately that the handhelds we were using. On the move via foot power it was always tracking accurately, with immediate response. I relied on the GPS for multiple significant events where accuracy was vital. I would compare the Suunto with the vehicle trackers (BFT) for accuracy and the X10 was spot on, always. Ahead of its time, but battery life was to be desired. Suunto customer service was over the top. They even sent me a couple extra bands and another charging cable for some reason. Since then I have had only one other Suunto, the Core military. Face is plastic and too scratched up to see in the sunlight clearly. It’s 11 years old and still works after going through several batteries over the years.
    I had the Apple Watch 5 for 2 days and sent it back. I just purchased the Suunto 9 Baro Titanium and the Garmin 6X Sapphire. One of them is going back. We’ll see.
    Off the bat both have the same vis through the sapphire display. Suunto feels way more comfy and not as bulky as the Garmin on me. If you sync to your phone the Garmin and Suunto response is immediate on notifications. I’m pretty the Garmin has more functionality because I have yet to go through all the settings, etc. The Garmin screens transition more fluidly and are intuitive. No issues at all with the Suunto touch screen even in the rain. Suunto GPS tracks more accurately than Garmin on the phone app, after the fact when synced. Way more accurately. HR monitors on both are in the ballpark. No expectations there. I’ve used Garmin and Suunto for years. 1st Garmin watch though. Going to be tough but I am leaning to Suunto because of a customer service experience over 10 years ago. I retired from the military 8 years ago but I still respect the hell out of Suunto’s quick response and follow up comms. My office has transitioned from crappy 3rd world countries to 4 walls with windows and friendlies (I think) all around. I still get out on occasion to the wilderness here in Colorado and appreciate good GPS functionality. I still use a compass, protractor, terrain association and always have a map as backup. Perishable skill for sure. We shall see. Again, great review.

    1. Good point about their customer service. Most of the issues I had with the Suunto were software related, so you may have a different experience than I had almost a year ago.

    2. Thanks for writing out your detailed experience. Really fun to read and you helped me see some of how suunto is as a company. I’m about to head over to Kyrgyzstan in a few months actually (taking the fenix 6 with me) so we’ll see how today’s flagship garmin watch holds up in a 3rd world country!

      1. Thanks and stay safe! I know it gets sketchy in that region I selfishly like Kstan because it was the first time I could get a beer after nearly a year in the other Stan. I thing GPS tracking technology is light years ahead of what it was when I was using the X10. Still, I may owe my life to a watch made by Suunto. FYSA, Suunto, I know you guys remember me, because I may have went off on your quality of product after that $600 watch bezel cover fell off while I was running around the FOB on day 1. Suunto stands by their products and owns any issues. No one, business or product is perfect. Suunto is real, and I am fiercely loyal. Service sells, period. The Garmin Sapphire Fenix 6x was sent back, but I am sure it was a good reliable time piece. I am on the Suunto 9 Sapphire, even though I will never use it to its capacity. It really feels more comfy and I am like 50 now. Dang that looks old when you type it out.

  16. Thanks for such a detailed review! Some of your points are opinionated, but they’re super useful. For example, there is no way to strictly quantify something like “aesthetic” or “clunkiness.” Those have to be sussed out and described, which you do nicely.

  17. Marcus, thank you for your very detailed and helpful comparison of these two great watches. I am a diehard Garmin user (I have 6 of their products), but I am pissed off with their current situation and lack of action on the outage. I don’t really think that I would switch to the Suunto at this point, but it’s always good to have and know your options! My Fénix 6x Sapphire is an excellent tool that has seen me through some fine adventures over the past months. It replaced a Fénix 3HR, to which there is almost no comparison. The 6X is superlative in every respect. I have tried several tools for GPX import and can recommend RouteCourse from the Connect iQ store, or Garmin Explore from the company. Both are strong apps for route planning and both work well in the field. I really appreciated your forthright and honest review. Thanks again. PK

  18. I just got the Fenix 6 Pro. Love it. GPS locks on quickly. HR all day and night, sleep tracking, can sync amazon music playlists so when i go for runs, i don’t have to take my phone. Prior, had a Samsung Gear sport. That was a great watch, bad battery. My Garmin lasts 4 days or so. That’s with at least 3 workouts, bluetooth music playing and all night tracking. I looked at the Suunto but it lacked features that I wanted. Note: Fenix 6 pro now tracks HR while swimming. Great review btw.

    1. What’s been especially great with the Fenix 6 is that they constantly keep updating it with new software and features. The updated widgets that came with version 10 (I believe) are much more informative and easy to read. I also like that I can now see sleep stats and altitude acclimatization stats right on the watch.

  19. I’ve bought the Fenix 6 yesterday, arriving on monday, based on similar reviews, but If I found this one earlier, It would definitely shorten my decision time.
    I am switching from a 5 year old AMBIT 3 PEAK SAPPHIRE, and I had to choose between Fenix 6 and Suunto 9. Where I live (Lithuania), I’ve found a deal on the regular Fenix 6 for 369 Eur. Suunto 9 is somewhat 500+ (to be clear most other offers of Fenix 6 are 450+) so that sealed the deal for me. And I was really happy with my AMBIT 3 (I’m not a sportsman I just like cycling and wearing something to look good with the suit), but just wanted a New year’s present for myself. So yeah… Thanks for the review, great, accurate, and I was first investigating SUUNTO since I’m much fond of the ruggedness and UNREAL battery times of the AMBIT3… but I’ve chosen garmin this time. The only thing I feel bad about is that it doesn’t have the sapphire version as default, and I’ve read reviews on gorilla glass 3 being scratched (the metal part on my AMBIT has a lot of scratches but the sapphire glass is pristine), but the fenix 6 sapphire version is like 600-650+ which does not translate into enough consumer value compared to the possibility to buy a 369 Eur regular fenix 6. Maybe I could buy the sapphire glass later, but I don’t count on it, I’ve read that if you break the glass you can buy another one and change it, so that’s it.

    Really looking to getting my garmin fenix 6 on Monday and start shaking off that incredible amount of fat I’ve gained during the last 8 months of quarantine 😀 Thanks for the review, glad you did it.

    Best regards,

    1. I’m sure you’re going to enjoy it. Farming has been great with software updates, it’s even better now than when I initially wrote the review

  20. Thanks for the review. 8 was considering the suunto when I first started considering sport watches. Instead I bought the Garmin instinct solar. I really liked the instinct, but after a week I decided it wasn’t really the right one for me, and I bought the Fenix Pro 6 Solar.

    So far Im very happy with it. For me though, and probably others, its the battery life and solar charging that were the differentiators. I like the idea of the samsung V3 watch and since I have a samsung phone the idea of that ecosystem is enticing, but I didnt want a watch that HAD to be charged every day like my fitbit.

    I also wanted a watch that worked fir all of the actuvities I enjoy, golf, skiing, biking, sailing, and some hiking and gym work. The Graphix 6 might have been a better choice because of sailing, but I decided the Fenix was enough!

    I would recommend it and I am happy with it. My only fear is the band breaking while my hand is outside the boat while sailing.

  21. Hi,
    that’s a great comparison and I agree with most of your points. However in few places I have completely different opinion.

    It is a bit unfair to compare Suunto 9 to Fenix 6 as the latter is smaller. When I compared both; Suunto 9 baro to Fenix 6X pro, turned out that Suunto 9 is much more comfortable to wear. It all gets to the way the base of the watch is shaped. Fenix 6X has sharp edges which aren’t comfortable if your wrist bone protrudes a bit. It helps if you wear it on the right hand as the Start button base doesn’t collide with the wrist’s bone. I know each of us if different but if you are boney like me, the watch shape makes a difference 🙂

    In the open areas both watches go almost head to head, however once you get into forrest, Fenix starts to lag behind. I do a lot of trail running in the Australian bush, and for every kilometre Fenix gets few seconds behind. It adds up. Recently I did a half marathon in the forest and at the finish line Fenix 6 was 1km behind.

    As you said Fenix 6 is way ahead of Suunto 9 with its functionality but the GPS accuracy and general comfort might me important to some people.

    P.S. I paid $800 for Fenix 6X pro and $300 for Suunto 9 … I guess that’s also an important factor.
