It is completely worth the price. The regular Apple Watch with aluminum has terrible glass. Very prone to scratches. I for one would always buy the stainless steel version for the sapphire. The ultra is 50 dollars more and better in every way. Looks, battery , durability, action button etc. for me the ultra is everything I wanted all the Apple Watches to be.

Apple care is insurance. It’s not worth it until it is. If your phone breaks then you are going to wish that you had Apple care. Just because you never broke it in the past doesn’t mean anything. Bottom line are you willing to take the risk knowing that it will cost you several hundred dollars to fix or replace if you break and or lose it? Personally I buy Apple care because I don’t want to have to spend another 1200 dollars if my phone is lost or stolen. Or 600 of it breaks. For me it’s worth the cost to offset the risk.

Didn’t have any battery issues on 10.1 or 10.1.1 so there is no clear answer. AWU2.

You can’t. 15 series only.

Your watch is possibly caught in a sync loop with something in your iCloud account. It’s continuously trying to sync something. This happened to me about a year ago and it ended up being reminders however it could be anything that syncs with iCloud. The issue was on the server side and only Apple tech support can fix. It took about a week working with a senior advisor but one they determined what was caught in the sync loop the fix was quick.

This could be your issue.
