Up for grabs is an Omega Speedmaster Professional Pre-Moon
145.012 reference with caliber 321 movement
260731XX serial number circa 1967 or maybe early 1968 production
Very good vintage condition case shows wear from being used, yes still has nicely defined lug with sharp edges. No corrosion or pitting.
Dial is original, and has aged to a dark tropical brown color which looks great in the sun or shade. Tritium markers are still intact and hands appear original, though look repainted in past. Unfortunately, the shows some damage around 7 and 8 plots, probably from careless handling during past service.
Caseback is in excellent condition. Crisp Seamonster, no major scratches anywhere, inside stamped 145.012-67
Movement is in excellent physical and mechanical condition. Chrono runs and resets at it should, the watch winds smoothly and keep good timing.
Very nice faded DON bezel as seen in pics
No box or papers. No documented service history. No bracelet or strap, but can include a new NATO at no charge.
