I took a big risk on this watch on eBay recently - described as non-running with very poor photos - about all I could see was that the case appeared beat up, the crown was a hideous replacement, the dial was black and said Seamaster on it, and it had a big logo on the case back. I’ve wanted a big logo and a black dial so I took the risk.. turned out to house this beautiful damaged dial. The crown is stuck tight, and when I opened it up the rotor was missing entirely. Serial number puts it in line with the big logo (1958). The movement sometimes ticks for a second or so when moved. So my question is - what should I do with it? I don’t care much for the back dial / gold case combination to be honest, and the case is pretty beat up with spots worn through to steel. What I really want is to re-case it with a stainless steel 2846 case and keep the big logo case back. I’m hoping to be able to repair the movement so I can keep everything else as-is. Is it an originality faux pas to replace it with a steel case? Is the case back likely to fit any 2846 case? The case back is just marked 2846/2848 with no version number. Any thoughts are appreciated. Thanks!
