1991 Omega Speedmaster 3590.50 Moonwatch “Yellow Patina, Unpolished”

Up for grabs is an Omega Speedmaster Professional Moon Watch

3590.50.00 reference with caliber 861 movement

482666XX serial number circa 1991.

Excellent vintage condition watch with minor signs of wear and age. Serial number is fully intact on lug. Case is unpolished.

The red wax on caseback was still sealed when this watch was purchased. I broke the seal in order to verify the movement, serial number, and physical condition.

Dial is original, tritium with gorgeous yellow patina. Damage free. Original tritium hands.

Bezel is in excellent vintage condition with minor signs of wear.

Caseback is excellent and stamped ST 145022

Crystal is hesalite Omega withOUT logo in center. This is correct for short period during 1991-1992 production. Some scratches from use.

Bracelet is in excellent vintage condition, reference 1479/812 and fits about a 7.5″ wrist.

Since the watch has never been opened before, obviously it was never serviced either. That being said, it currently runs well showing about -7 seconds on timegrapher with ~290 amplitude and chronograph runs and resets properly.
