I’ve used Apple Watches since the first waterproof one - series 3? - no issues. I found my Garmin fenix 6 was terrible for laps, I’m currently on an ultra (1) and it’s fine. I sometimes end up on an odd length but usually ok.
I’ve had my epix pro for 3 years and it’s great watch. The screen is just a bit too dim for my aging eyes and I dislike how poorly the amazing data Garmin collects is presented in the app. Making the switch back with AW3 but not going to sell off my Garmin because I still love it
I have the series 3 still
My apple watch 8 has done a few hundred thousand yards swimming over the last 2 years and still works perfectly if that makes you feel better. I also used to swim with my Apple watch 3 all the time and never had issues either.
I'm with you. The only reason I even bought one was I got a used S3 so my older iPhone would unlock automatically while I was wearing a mask at work, then I thought the workout tracking was nice so I got a new S7. Now that I don't wear a mask regularly, it's strictly a workout tracker. I don't think I'll buy another Also it makes me MISS a lot of notifications due to how I have it set up. Some whatsapp contacts are set to silent when they send a text. So it will (silently) display the text on watch screen when I am not looking, and then consider that to count as "well he's seen the notification, time to clear it from his phone lock screen as well" So I just end up missing those entirely. Without my watch on, they stay on my phone lock screen as they should
I had an Apple Watch Series 3 and ended up getting the forerunner 965 earlier this year. I love the Garmin because it doesn’t have all the extra features of the Apple Watch and the battery life is outstanding. I realized I was only using my Apple Watch for exercise and didn’t like the extra notifications it gave me.
