Omega 344 Description
The Omega 344 is the chronometer-grade version of the brand’s “bumper” automatic movements that feature a small sub-seconds dial. Produced in the early 1950s and used in top-tier models like the Omega Constellation, it is the direct counterpart to the sweep-seconds Cal. 354. This robust and highly accurate movement combines the classic aesthetic of a sub-seconds display with the innovative bumper winding mechanism.
