I have very little knowledge aboput watches but to be honest I had sold this watch before. It was sent back as there is a problem with the ring that holds the back plate on. Please see pic 7 i have marked the problem in red arrows. To someone that repairs and collects watches I would presume this would not be to big a problem to fix but like I said I would not realy know. The watch itself and the mechanism is very nice though. size excl crown 38x36mm
