Omega Oversize Ref. 2505-23

The Omega reference 2505 belongs firmly to the second category. Introduced during the post-war years, it was an exceptionally large watch for its time. At 38.5 mm, its proportions were dramatically different from the conservative standards of the late 1940s, giving this elegant time-only Omega a presence that still feels remarkably contemporary today.

What makes the reference particularly fascinating is the balance Omega achieved between size and elegance. The large steel case is not simply oversized for the sake of being large: its slim profile and beautifully curved lugs give the watch an unexpectedly refined silhouette. On the wrist, it has the presence of a modern watch while retaining every element of classic mid-century design.

This example is reference 2505-23 and is powered by an early Omega hand-wound movement, recently serviced and ready to be enjoyed.
The real personality of this watch, however, lies in its dial.

Time has transformed the original surface into something far more expressive than a perfectly preserved dial could ever be. The warm patina has developed naturally over the decades, creating soft tonal variations that give the watch an unmistakably vintage warmth. Depending on the light, the dial takes on subtle shades and depth, making the entire watch feel alive rather than static.

This is precisely the appeal of a great vintage Omega: not artificial perfection, but authenticity. The signs of age are part of the object’s visual identity, telling the story of nearly eight decades without compromising its elegance.

Completed by a brown lizard strap and an original Omega buckle, this is a wonderfully wearable example of one of Omega's most charismatic oversized references.

A true mid-century Jumbo, with proportions that were extraordinary then and remain compelling today.
