Omega Oversized Chronograph

Omega Oversized Chronograph

Why We Love It

Vintage chronographs are, in a word, awesome.

These little machines were witness to some of the most momentous occasions. From triumphs at the racetrack to man’s conquest of space, they were there, timing history.

At 37mm, this Omega Reference 2475 chronograph features a stunning silver tone dial with dual subsidiary registers. The dial is beautifully accented by applied pink gold dart markers and dauphine hands. 

Mechanically, it is powered by the Calibre .320 manually winding chronograph movement, a two-register version of the legendary Calibre .321 column wheel chronograph movement used to power the original Speedmaster Moon watches.

This mid-century chronograph has just the right amount of patina and wear, proving without a doubt that this beautiful oversized piece has witnessed a lot in its life - and is ready to accompany you for a whole lot more.

The Story

Omega produced their first chronographs as pocket watches as early as 1885, and by 1913 were putting them on straps. In the 1930s, the quality of Omega's chronograph movements was improved by the acquisition of famed manufacturer of chronograph ébauches, Lemania.

The association with Lemania and Omega was a long-lived one, spanning nearly four decades, and is marked by the masterful hand of Albert Piguet, Lemania's head movement designer, who conceived such venerable calibers as the caliber .321.

All in all, vintage chronographs such as this from Omega are amazing examples of the brands rich history and development.
