Surely Apple will have some kind of concierge service for Edition owners to facilitate all of that. They're apparently making a lot of changes to deal with these watches.
FWIW, sometimes even Rolex or Omega owners buy a new watch that has an issue early on, and you have to send the thing in for a repair that takes several weeks, unless maybe it's less than 30 days old, where the dealer will just replace it, if they even have one in stock.
