A:AnswerWatch has an always on option that dims, but is viewable. If you’re looking to save battery, always on can be turned off in which case screen will be off until you wake by lifting your arm. No need to touch screen to wake.
A:AnswerMy understanding is because you have the cellular capability. Having this means you don’t need to keep your phone nearby.
If you just have the GPS function you don’t have to pay that but you do need to have your phone close by.
A:AnswerThe watch should work with iPhone XS as long as the phone is updated to iOS 16.
The only other accessory you need is a USB C charging block. It comes with the cord. Any other bands etc are optional.
