Hi, It is offered a $350 which feels kinda cheap. The description says :"Original waffle dial, rose gold numerals are accented by the genuine croc strap. The stem does not "catch" when pulled out, but does set and run " I notice the last "A" does not have a flat top but if I remember right it was often the case for models of the 50s. Thank you
Looks like a 2577 Seamaster , powered by a non chronometre 354. The waffle dial was from Omega (original) but refinished at some time in the past. Hands and markers are correct. It should have a screw in caseback, I believe. Keyless works need repair. (or wrong stem maybe??)
