I've had a Fenix 3 sapphire since 2016 and it's still just as good as the day I bought it (used). Best $300 ever

Im you a few weeks in, and have been a fenix user since the fenix 3 came out. But the apple universe is so practical, so i went the Awu3 way now. After a few weeks of owning this watch, i find there is pros and cons. Pros: the apple universe.. Cons: almost every free insights you get from Garmin is a paid app on Awu. I use Runna for running, i find it to be the best for running and kind of like the Garmin running plans. Im trying to figure out the WorkOutdoors app, but im not that big a fan yet.. As i live in norway and hiking and skiing is big, i found that just using the strava app works way easier (for now) if you use strava too.. As for body battery, bevel or Athlytic is ok.. AWU is not so good on sleep tracking, so i would rather just listen to my body and use the BB as an indicator. My honest opinion a few weeks in. The AWU is a really good day to day watch with workout tracking built in, but the Garmin watches are really good sport watches. Im giving this watch a year, and if i still like and get used to it, ill probably keep it. If not im going back 😊

I don’t understand how. It seems like it tracks sleep in intervals, and if i dont sleep at that given interval i get a bad sleepscore.. or if im just laying down, it thinks i had a good nights sleep even though i just slept 3 hours that night.. garmin is not good, but it felt overall better.. but it could be that im adjusting to the new watch

I went fenix 3 -> AWU -> fenix 6 -> fenix 6 & AWU2. Garmin is the better watch. Better for recording outdoor stuff. Battery is once or twice a month with running every day. It’s great. You never sweat it. But half the days it won’t connect to my iPhone. I miss calls and can’t reply to texts. Syncing to my phone is also a hassle (have to turn the watch on and off half the time). AW is an extension of my phone and a distraction. But I can reply to texts without my phone. It helps reduce screen time because I can leave my phone across the room. It has better complications for the most part and the ultra at least matches my fenix. I had to add apps to get heart rate and steps on my main screen but they update and work. The dive app is cool (visiting my parents in the keys and snorkeling). I ski a lot and the ability to unlock my phone with goggles and a mask on is huge. Also Apple Pay. Picking one? Hard choice. But I bought my fenix 6 used for $300 a few years ago and added the AWU2 refurbished from Apple (so 100% battery). I’m keeping both.

I still use a Garmin Fenix 3 HR. I like the quick release charging adapter. I have it on a quarter turn mount that allows me to swap from arm to bike in seconds.

Good to know. I have a Polar H10 chest strap for workouts, so that will work. I had a Fenix 3HR YEARS ago when I didn’t know what I was doing, but for some reason, that watch helped me get into the best shape I was ever in. I think seeing all the data in one place, with context added, encouraged me to get after it more.

I've owned a Fenix 3, Fenix 5 and Fenix 6. Each one glitched and died at about the 2 year mark. I've given up on the Fenix line entirely.
