Just picked up a Seiko 4205-015K (SN:120135) . Its had some unhappy refinishing attempts and the bezel is loose,both horizontally and vertically, any idea how to fix this? A new gasket perhaps? I cant seem to find one!
Looks like the crystal retaining ring is broken - there's what appears to be a crack in it, in pic 1. If the ring is loose, maybe that's why the bezel wobbles?
I've taken a few 6309s apart, and the 4205 looks to go together in a similar way. A couple of them have had cracked retaining rings or worn bezel O-rings, causing the bezel to wobble. Parts are readily available from eBay sellers in the Philippines for the 6309. Not sure about the 4205.
Probably the best thing to do, Leon. Go for a 6309 (plenty of aftermarket parts) or a 7S26 (007, 009, etc. - newer, so movement should be OK). If you want a slightly smaller watch, the "submariner" is a good choice (SKX033, with 7S36 movement).
