I’ve just acquired a Seiko SM300 Sbdx017 and as luck would have it has been knocked in transit and is gaining 30 seconds a day; making it a candidate for adjustment.
It has an aftermarket sapphire so even if it was not just out of warranty I am guessing that Seiko themselves will not touch it.
l’m a bit worried about entrusting the case and crystal arrangement to a non specialist and I know that Cannop, who first came to mind, is not taking new work right now.
So I would appreciate suggestions, including waiting for him, which I am more than willing to do.
Might also be magnetised?
