I can tell you how long it will last. My Spring 2015 Series 0 42mm Stainless Steel Apple Watch is not eligible for the new WatchOS this month.Lucky for me, right underneath where the buy button would be is an option to trade in my Apple Watch toward a new one. I input my serial number, and they are offering me... $25...

So, a little over 3 years for an $800+ watch. My Citizens are that old and don’t need batteries or winding.
Probably not for me. Thanks.
