Omega Chronograph 18k Pre 321 Jumbo 1944

The Pre 321 cal. 27-CHRO-C12: In the early 1940s, Omega commissioned its sister company Lemania to produce a new chronograph mechanism that would be as small as possible and yet capable of totalizing the hours in a 12-hour counter.

At the time, neither Lemania nor Omega could have imagined that this would probably be one of the most important developments in the company’s history, as it was the forerunner of the caliber 321 that powers the legendary Speedmaster.
