Omega Speedmaster Racing Chronograph Automatic
Unlike more modern versions, the original 1957 Speedmaster that was powered by the legendary Omega caliber 321 hand-wound movement featured the usual three hands for displaying time, as well as three chronograph sub-dials with no calendar. The 2012 Omega Speedmaster Racing (ref. 326.32.40.50.06.001) chronograph takes the iconic collection back to the classic layout.
