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 from 1964 when the first reference 105.012 with "screwed-lugs" case was introduced until today. Probably the most recognized 3-reg chronograph desired by every collector and every man! This particular example boasts with probably unpolished case in outstanding condition, showing almost no signs of wear and use, rare and collectible "doctor's" bezel with pulsation scale (an original one with a line, not a modern service part missing this important detail!), and stunning dial with tritium markers in warm yellowish tone.

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:
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.
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.
