Up for grabs is an Omega Speedmaster Professional Moon watch
3570.50.00 reference with 861 caliber and serial number engraved on lug. The movement has correct 18 jewels, instead of 17 as in 861 of pre-1995 vintage. Omega used 18 jewel 861 movement from 1995-1997 before switching to caliber 1861.
483481XX serial number circa 1996 production
Excellent used condition is clearly unpolished. The 1 o’clock side of the case has a small ding and is disclosed, but you will basically never see it while wearing.
Dial is excellent tritium with vivid yellow patina. No scratching, bubbling, discoloration on dial. Hands are tritium and original.
Bezel is in very good vintage condition. Crystal is original Omega hesalite with logo in center.
Caseback is excellent with original finish. Stamped st 1450022.
Bracelet is nice 1499 with 842 ends. Fits about a 7.5″ wrist.
No documented service history. No box or papers. The chrono starts, stops, and resets. Inside caseback is marked “7/2022” so assuming a service has been performed then.
