Why We Like The Garmin fenix 8 AMOLED Sapphire Sport Watch
Whatever plateau we're breaking through, Garmin's fenix 8 AMOLED Sapphire Sport Watch is tracking and driving our every step. The bomber, submersible construction meets the moxie required for rugged terrain and technical pursuits, while the heart rate, ECG, and blood oxygen saturation metrics clue us in to how our body is handling the demands. With 145 hours of juice in max battery GPS mode, this watch outlasts the sun time and time again, while the built-in LED flashlight comes to save the day when our headlamp flickers out. However deep into the backcountry we go, the SatIQ tech keeps our position locked in without draining the battery.

Great Watch
Upgraded from my Fenix 7 to get the full color display. Much more vibrant and readable, with excellent battery life (about 3 weeks with moderate GPS use). As with prior models, it is a bit of a chore to get the menus, display fields, and the watch face customized to your liking, but after that, it just works, with excellent functionality. Main hesitation in recommending it is just the price. Unless you use the microphone/speaker functions (which I do only occasionally) the main upgrade from recent models is the display and battery life.

I love it. I use it everyday. I charge it once a weekend but I think I could charge it once every 2 weeks which is a total upgrade from my apple watch that I had to charge every night. I don’t use the sleep app but there’s so many features that I don’t even realize how useful it is!

Absolutely worth the upgrade
All the functions I expected and love, plus the functionality of the touch screen, and voice recognition is definitely worth the upgrade!

Having issues with connectivity.
I got the device a week ago and already facing connectivity issues- the device Bluetooth fails to connect to my phone and twice have failed to upload activity. the Online help suggestions are not helpful at all- asks me to refer to the manual which i dont have!

So far, so good
My next 24 hour event isn't for another month, but so far this has been an excellent watch with long battery life and great tracking. Added benefit of the built in LED flashlight has come in handy many times during early morning rides digging around in the back of the car for lost items. Great for an experienced outdoors person for long treks.

Battery Life is exceptional
I had the Epix before and it was a great sports accessory. This does all that and more. The battery life is the most noticeable immediate difference. I use this for everything, although apparently I need to sleep more and I am really out of shape ... lol! This watch will work for any stats geek whilst still being popular with the weekend warrior who likes to smash out activities and track them.

Exceeds expectations.
Every feature about this watch, I love. There’s two features that I wish it did have. One; I wish it had a “Find My” iPhone feature. Two;would be the rucking fitness activity. Otherwise the battery life exceeds my expectations, the fit of the 51 mm is amazing, and I am continually impressed by the durability of this thing. I’ve whacked it several times and I thought each whack was going to leave a permanent patina, but so far nothing has happened.

The watch is light, unobtrusive and comfortable. It does an excellent job tracking my exercise and sleep. It is much more accurate tracking my swims than my previous Fenix 5

First time Garmin owner
Coming from an Apple Watch Ultra I wanted two things. Longer battery life and better analytics when tracking workouts. The fenix 8 does those both of those things very well. I am so used to having to charge my watch every night and it took me a while to remember this one doesn’t need it for at least two weeks! I have also pleasantly enjoyed the flashlight, not something I thought I would use as much as I have been. I thought I had made a mistake getting the 51mm considering my wrist aren’t the biggest but it does not look cumbersome or heavy on my wrist.
