Omega Speedmaster Moonwatch Co-Axial Chronograph 311.30.44.50.01.002

The OMEGA Speedmaster Professional is renowned as the iconic model that journeyed to the moon. At first glance, the 311.30.44.50.01.002 looks quite similar to the Professional, but a closer inspection reveals some interesting enhancements

Firstly, the text below “Speedmaster” reads “Co-Axial Chronometer” instead of “Professional.” This version of the Moonwatch introduced the Co-Axial movement a decade before it was added to the Professional line. The 311.30.44.50.01.002 is powered by the OMEGA Caliber 3313, a Co-Axial vertical clutch automatic chronograph, which can be admired through the exhibition case back. The case is slightly larger at 44mm and features a date window at the 6 o’clock position.
