1970 Omega Speedmaster Professional Ref.145.022-71 Stepped Dial

About our pricing

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.

    Measuring a watch

    It is always crucial to understand the size of the watch, especially when it comes to vintage watches which are generally considered as too small in comparison with what watch industry offers today. For example, the original Patek Philippe Calatrava introduced in the 1930s was only 31 mm in diameter, while today's classic Calatrava is 39 mm. When you think about 8 mm, it doesn't seem to be a big difference, but believe it is.

    In our condition reports we normally disclose three most important parameters as follows: diameter without crown / lug-to-lug length / lug width. 

    Diameter without crown

    It is, so far, the most important measurement to understand the size of a regular round-shaped watch.It helps you to understand proportions and overall look of the watch. It is important to consider width of the bezel and color of the dial, because certain combinations may make the watch look bigger, while some other smaller. It is all very individual, however there is common understanding:

    Lug-to-lug width

    This parameter will help you to understand whether the watch is comfortable for wearing. You should compare lug-to-lug width with the width of your wrist, and if lug-to-lug width is smaller or equal, then this watch shall be comfortable.

    Lug width

    This measurement is defining what size of strap you need for the particular watch. Depending on era and manufacturer you can find watches with lug width between 14 mm and 24 mm. Most common sizes are 18 mm and 20 mm.
