What do you do with the Apple Watch? :D\n\nI bought a series 3 when they were pretty new. Main reason was as a swim tracker. All the reports then rated the Watch as the best overall option at the time. It knows what stroke I'm doing, counts laps... pretty impressive.\nIt seemed expensive for just that, but I'm Worth It! :D\nAt this point, I had two issues with the Series 3 water resistance failing, and when I took it back to Apple, they gave me the friendly bump and sent me a new Series 4. I haven't had any problem with that, though the battery is starting to get a little iffy when I run GPS during my swims. An hour of that will eat about 25% of the battery.\n\nAnyway, for the Heath and Fitness tracking features and other side benefits of being able to control many Phone features from the Watch (including as a remote screen when taking a photo!) I honestly don't see myself giving it up.
