When the Speedmaster Professional went to the Moon in 1969, a legend was born – the Moonwatch. OMEGA's catalog has been built around that great, manually wound, lyre lugged cased chronograph ever since. Yet for the fans of the Moonwatch who found the classic Professional case a bit too large in diameter and the lauded manually wound caliber a bit too cumbersome, OMEGA introduced the Speedmaster Automatic, otherwise known as the "Reduced," in 1988. 

At its core, the Speedmaster Reduced was just that – a reduced sized Speedmaster. As such, the twisted lyre lugs stayed, as did the matte black dial with stark white accents, tri-register chronograph configuration, and external tachymeter bezel. Though now the watch would be executed at just 39mm, three millimeters smaller in diameter than traditional sizes at the time, and inside the watch an automatic mechanism – the OMEGA caliber 3220 based upon the ETA 2892-A2 - would provide power in comparison to a traditional manual-wound movement.
