Up for grabs is an Omega Speedmaster Professional Moon Watch
3590.50.00 reference with caliber 861 movement
Circa around 1990 before Omega started engraving the serial number underneath the lug. Since the factory red wax seal is still intact, I did not want to break the seal to find out the exact serial number.
Excellent vintage condition watch with minor signs of wear and age. Clearly unpolished. No dings or dents. Very mint.
Dial is original, tritium with nice yellow patina.
Caseback is excellent and stamped ST 145022
Crystal is hesalite Omega with OUT logo in center was correct for 1990-1991 pieces. Minor scratches from use.
Bracelet is original Omega 1479 in nice and tight condition.
No box or papers. The watch winds smoothly, runs at +5 seconds with ~310 amplitude on timegrapher.
