The OMEGA Speedmaster is one of OMEGAs most iconic timepieces.

There is a small seconds sub-dial at 9 o'clock, a 12-hour recorder at 6 o'clock and a 30-minute recorder at 3 o'clock, as well as a central hour, minute and chronograph seconds hands. The transparent tachymeter scale on the sapphire crystal is illuminated from beneath by an aluminium ring filled with Super-Lumi Nova. The 42. 40 mm stainless steel case is presented on a matching bracelet. At the heart of this chronograph is the exclusive OMEGA Co-Axial calibre 3330.
