1970 Omega Speedmaster Pre-Moon ref. 145.022-69 “DON Bezel”

Up for grabs is an Omega Speedmaster Professional

Reference 145.022-69

296022XX serial number circa 1970 production

This is a Pre-Moon transitional model with cal. 861 movement.

Excellent vintage condition case case with sharp lugs. Previously polished. 

Original step dial with nice patina on plots. The dial is a very dark brown shade, but I wouldn’t call it tropical. The hands appear to be aftermarket replacement. 

Bezel is correct and original “Dot Over 90” with some signs of wear.

Caseback is original with legible Hippocampus on back, stamped 145.022-69 inside.

Crystal is Omega hesalite with logo in center.

The bracelet is original Omega 1506 flat link with one 516 end-link and one 633 end-link, replaced later on presumably. The bracelet is long and fits a large man’s wrist. Clasp is dated 1970. 

Service history is not known. Currently its winding smoothly and the watch shows -8 seconds with 330 amplitude. Chronograph runs, stops, and resets back to zero.
