The only information we have about the watch is that its an Omega Seamaster, and is supposedly from 1956. Any help would be appreciated.
I've not seen that one before. You need to remove the case back and there should be a model number on reverse side. Also you should record the serial number and calibre number which will be engraved on the movement
It's unlike any Seamaster I've seen before, especially for that period. Help us help you. Read this. https://omegaforums.net/threads/vintage-omega-posting-guide.383/
1966 would be a better bet. Looks a lot like a ref B6687 that's had the lugs cut off and the bracelet attached. Norman Morris had a pretty free hand at creating unique styles for the US market.
