Omega Speedmaster 125

The calibre 1040 was the first self-winding chronograph movement used by Omega and calibre 1041 was chosen for and only used in a commemorative edition celebrating the company's 125th anniversary. See Omega Speedmaster 125. Exclusively produced for Omega by Lemania.


The OMEGA Speedmaster 125, introduced in 1973 to celebrate 125 years since OMEGA’s foundation, was the world’s first chronometer-certified automatic chronograph watch. It was not a revolution but an evolution from the original Omega Speedmaster of 1957. The Speedmaster Professional reference ST 145.022 was not seen as the future by OMEGA. They had steadily been new versions of the Speedmaster, starting with the Mark II in 1969, still with caliber 861, and had gone automatic in 1971 with the Speedmaster Mark III.
