··Omega Qualified WatchmakerI don't know what thread you are referring to, but if a specific watch is "Bienne only" or not depends on 2 things:
1 - Swiss produced case or "national production" - If the case of the watch is not a Swiss made case (and is a locally produced case, what Omega calls national production) then Omega says this should go to Bienne regardless of the movement.
2 - Caliber restrictions - there is a list of specific movements that Omega considers "Bienne only" so one would have to check that list and see if it's on there or not. If it is, then the watch would be sent to Switzerland, and if not it can be serviced locally.
In this specific instance, it is unlikely that the case is national production, and the Cal. 564 is able to be serviced locally.
Note that these rules apply to official Omega entities only, so I do not follow these as I'm an independent watchmaker, and I can choose to service Bienne only calibers, or watches with locally produced cases if I wish to. In fact I just finished an Omega Century that has a locally produced case.
