Hi,
No problem with setting time or winding the watch (some Automatics can be wound others not, like Seiko or Orient). Also setting the date is no problem. The crown functions ok, it is just not "screwable" anymore. This is a cosmetic thing, because replicas are not waterproof like gens. If it would happen on a gen watch, you could not dive / swim anymore, because of the crown not being screwed tight.
So the watch works very well, it is just the look that sucks a bit, because the crown doesn't sit "right" (you see a bit of the stem, but not much).
As it is a replica and was never waterproof, it is just as functional as before, but ....the look
Regards,
Bernie
