to a new Apple Watch install all the programs on the new one?
Thanks :)
I don't think apps are "backed up", well I do know they are not backed up on an iPhone so why would they be on the AW?
I always set my new AW up as "new" vs restore:
it's fun to go through the menus and see options one might have forgotten
doesn't take much time
don't lose data (except watch face customization)
there have been posts here where problems are transferred to the new AW

Regardless, enjoy your new AW
 
It does restore everything, I think technically the apps are re-installed from the App Store, instead of being part of a backup, their data is restored though.

It will walk you though everything. If you have any Apple Pay cards, you'll have to re-authorize, maybe with the code from the back, but you won't have to re-enter the card numbers.

I usually upgrade every couple years, and don't think I've started from new on any of the 4 or 5 watches I've owned. and not had any problems.
