Click here to contact me and make this historically important vintage Omega 33.3 CHRO yours today! SOLD
On offer here is this highly coveted, all-time vintage Omega classic reference 2077-4 chronograph powered by the famed manual wind caliber 33.3 CHRO movement. The 2077 began production during WWII and is an oversized water resistant, military-style chronograph with screwed back and round pushers. It measures an impressive 38mm in diameter and is a direct progenitor of the famed Speedmaster line.

As far as I can tell, all these Omega 33.3 CHRO movements were made in a few limited runs in the 1940s and then cased up at different times, some quite a few years later than the movement serial would indicate. This example is from the 10.8 million batch (ca. 1944) but likely dates to 1950 or so, as denoted by not only the fourth series indicator in 2077-4 but also the style of the Arabic “12” & “6” and dagger markers dial.


I believe that this is an older redial — perhaps 1960s-era based on the style of the OMEGA font? — and, as you can clearly see, it has more than a little aged vintage character to it, both of which are reflected in the asking price. Still, it’s quite charming on the wrist, with a super strong case, and if you happen to have an original dial that fits this case and caliber you’ll certainly be in clover. 😉

Overall, the watch is in Very Good well-worn vintage condition and the complex 33.3 CHRO movement has just come back from a full overhaul, so it’s ready to wear and enjoy, with all timekeeping and chronograph functions operating well.
