Hi, all. I'm considering buying this Seamaster. Caseback reference is 2577-12 SC, and 13M serial number dates it to 1952/53. It's a cal 354 bumper, showing lots of tool marks but recently serviced. I've looked at many (many!) images of various 2577 variants. Lots of waffle dials, some crosshairs, plenty of repainted examples. So many, in fact, that I'm having a hard time sorting out whether this dial is original or not. So, hoping for some advice here. I can see that the seconds hand Is wrong; maybe all the hands? Thanks in advance for your comments.
