1971 Omega Speedmaster Professional Ref.145.022-71 Stepped Dial

Authenticity Guaranteed / 14-days Inspection Period / 1-year Warranty

Original outer carton box + plastic box + extract of archives

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.

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 movement is running perfectly showing perfect timekeeping results. Technical warranty: 1 year.
