Early Omega “Jumbo” references from the late 1940s and early 1950s represent some of the most desirable and wearable vintage Omegas available today.
This Omega Ref. 2640-2 from 1950 is a perfect example of why.
At a time when most watches were produced in the 32–34mm range, this piece stands out with its oversized 36mm case. That extra presence, combined with beautifully flared lugs, gives the watch a strong wrist presence that feels incredibly modern while retaining all the charm of the era.
The dial is where this watch truly comes to life.
Originally silver, it has aged into a warm tropical tone that gives the entire watch depth and character. The patina is even and attractive, creating a rich golden hue that works perfectly with the steel case and brown leather strap. The applied art deco numerals and markers add another layer of design interest, giving the watch a distinctly mid-century aesthetic that feels both elegant and slightly playful.
This is not a flat or lifeless dial. It is full of warmth and variation, exactly what collectors look for in a tropical example.
Inside sits the Omega calibre 283 manual wind movement, a robust and reliable workhorse from Omega’s early post-war period. It delivers a pure, mechanical experience that perfectly suits the character of the watch.
