I personally went with Apple Watch Ultra 3 since I have an iPhone, and it can last about 48 hours for me. Previously I had Garmin watches, which were amazing. The only reason I switched was because I wanted cellular. But something like the Garmin Forerunner 970 is very nice.

honestly no. I think I would, but really no. I think it's the fast charge that does it for me. I just charge my watch each time while I'm in the shower. I have been taking my garmins off during my showers, so this is no different. It charges the Apple Watch fast enough. And concerning exercises, my previous Garmin was a 945 LTE. I did triathlons with it. But the Garmin had actually less battery during exercise than my Apple Watch Ultra 3 because of the LTE. I'm sure the Garmin would have done better if I turned off the LTE, but with it the Apple Watch does it better. Garmin just has a much better battery life on smartwatch mode. I would of course not recommend the Apple Watch Ultra 3 if you are doing Ultra marathons or multi-day activities. But that's not for me, I haven't done an exercise longer than 10 hours for now in my life.

Similar story! My wife gifted me a Fenix 8 Pro day before yesterday on my birthday. Have my good old FR945 LTE.

FR 945 LTE. My brother showed it to me. When I got back from deployment in 2022, it was on Amazon for $239. Perfect post-deployment gift to myself. It has so much information, maps, cadence, music, etc.

Fenix 8 47mm Sapphire. I've had a range of Garmins (Forerunner range: 35, 235, 935, 945, 955) but the 970 didn't appeal to me (accent colour on side and domed glass) so I got my first Fenix and first AMOLED watch (solar was thicker than my 955 which was already a bit thick under clothing). Love the look of the Fenix a lot more, plus better battery life

I have the Forerunner 945. The battery is eternal, watch face isn’t too big (small female wrist here), and it doesn’t everything I could want a watch to do. It interacts with and displays my varia radar and power meter pedal data as well as with my Wahoo trainer without issues. It has pool and open water tracking and uploads workouts. The HR is pretty spot on even in the water. The only time it fails me is when I’m climbing out of the saddle and put a sharp bend in my wrist. Watches use a different algorithm to measure gain than the computers, so I believe my Edge between the two, but if you yse Strava you can have it elevation-correct after the fact.

This location seems like it would chafe like the dickens swimming and running. Jelenew makes a bra with an hrm hole to help keep it in place. I upgraded to the FR945 from my 2-series when I got into triathlon because it has openwater and triathlon activity tracking modes and a massive battery life to get me through an IM. It’s not perfect but it’s pretty darn good in open water. Also, Form 2 goggles use a HR sensor on your temple. They work best with an open water GPS-compatible watch for tracking, but the HRM is independent. I just got a pair so too soon for me to give my own review

My Garmin Forerunner 945 has really inaccurate (underreported) heart rate when skiing, especially skate, unless I use a chest strap. I'm not sure if the newer 9x5 models are better. But it does has activities for both.
