1970 Omega Speedmaster Professional Ref.145.022-71 Stepped Dial

Legendary chronograph qualified by NASA for their space missions, bearing famous caliber 861 - the improved successor of Cal.321, another legendary movement made by Omega. The design of this truly iconic chronograph basically remained unchanged since 1964 when the first reference 105.012 with "screwed-lugs" case was introduced. Probably the most recognized 3-reg chronograph desired by every collector and every man.

This particular piece is a true "barn find" coming from its' original and the first owner. It is notable for a knife-sharp unpolished case showing normal traces of wear, absolutely immaculate stepped dial with pleasant tritium tone and perfectly running movement. The reference 145.022-71 is particularly interesting because it was the last model produced with collectors' beloved stepped dial. Unlike 145.022-69 produced in significantly bigger numbers, these pieces rarely pop-up in absolutely correct and untouched condition.

The watch is sourced from the original owner and is completely untouched (except cleaning). The movement is running perfectly showing perfect timekeeping results. Technical warranty: 1 year.
