Up for grabs is an Omega Speedmaster Professional
309985XX serial number circa 1970
Late production Pre-Moon, transitional model with Cal. 861 movement.
Excellent vintage condition case. No major dings or dents. No corrosion or pitting.
Dial is tritium with very nice yellow patina. It is smooth tritium dial, opposed to the step dial these are usually seen with. The large seconds hand appears to be a replacement.
Bezel is in excellent condition. I believe it is period correct and original with late production pre-moons not having DON.
Caseback is excellent, very defined, stamped 145.022 – 69
Watch runs, winds, and chrono runs and resets back to zero. It is not keeping great time and is recommended to be serviced soon.
Comes on brown leather strap with steel buckle.
