You might be the first person I have heard have a good experience with the watch. All I remember hearing was how fast the battery drained and syncing issues. I like the link because it allows you to track data AND play music. If thats not something anyone is interested in I don't see the point unless you really hate the phone in pocket.
The older Apple watches def had battery life issues. The newer Series 6 and 7 has much better battery life. I charge it to 100% overnight and when my round finishes I’m usually at 40% still. They key is a full charge before you start the round. Plus the display. Speeds things up. A lot for me.
I average about 84 shots a round. Can’t speak for anyone taking 102 shots. Lol
