For sale is an early 1950s Omega Seamaster with a bumper automatic movement. The watch is in nice condition, but it does have a service dial and crown. See below for more info. Dial: I believe it to be an Omega service dial. Dial features non-luminous (non-radium) markers and hands. Missing Seamaster text is expected for an early Seamaster. Case: Original 34.5mm 2577 reference case is in nice condition but has been polished. Crown: Omega service crown. Crystal: Signed Omega crystal (see small Omega logo etched in center). Movement: Bumper automatic movement runs, winds, and sets well, but service history is unknown. The caseback is stuck too tight to get off with a rubber ball and I don’t want to risk scratching it with a wrench, so I don’t have movement photos. It should be a 351 or 354 caliber movement dating to the early 1950s (potentially 1948-49). Strap: Comes on the 18mm black DeBeer leather strap pictured. Price is $500 (reduced from $650) shipped globally. Bank transfer/Wise for payment. OF seller reviews are here. Returns are accepted if the watch is grossly misrepresented. Watch is located in the USA.
