Product Description

Omega Ref. 2403 — A 1940s Vintage Classic

The Omega Ref. 2403 belongs to an important period in the history of Swiss watchmaking, when Omega was establishing itself as one of the leading manufacturers of precise and reliable mechanical watches.

Dating from the 1940s, examples of the Ref. 2403 are a beautiful representation of Omega’s understated vintage design language. One documented example of the Ref. 2403 / 1 dates to approximately 1943 and is powered by the renowned Omega Calibre 28, a hand-wound mechanical movement from one of the company’s most important early post-war calibre families.

With its approximately 35mm case, the watch reflects the proportions of its era. Compared with modern watches, the dimensions may appear modest, but on the wrist they create the elegant and balanced presence that has become increasingly desirable among collectors of vintage Omega.

The Omega Ref. 2403/1 is therefore more than simply an old wristwatch. It represents a fascinating chapter in Omega’s history and the evolution of Swiss mechanical watchmaking during the 1940s.

For collectors, its age, classic proportions and period-correct Omega movement make the Ref. 2403/1 an appealing example of mid-century vintage watchmaking — discreet, elegant and deeply connected to the history of one of Switzerland’s most respected watch manufacturers.
