That's good to know. I'm still into mechanical watches but I like them on the thinner side. Maybe some day when they hold a charge longer I'll try an electronic one.
This is actually my third AW (original series and the fourth series) and to be honest since I've started wearing Apple Watches, my other watches just sit in my watch case wondering when I'm going to wear them..LOL
I'm not exactly sure how long I could go without charging this AW, but I estimate about two days, however I charge it every night like I do for my iPhone. I remember when we never had to charge our home phones or earbuds either...LOL
