These vintage Omega Seamasters with original black dials are becoming hard to find. This 1955 example measures 34.5mm and has a clean 14k. gold filled case with usual tool marks on the rear. This watch retains the correct notched Omega winding crown. The black original dial is stunning; having raised gold toned Breguet style numerals and arrow markers along with Dauphine style hands. The caliber 500 automatic movement sparkles after a recent cleaning and is accurate. The pictures say it all.
