The OMEGA Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand’s adventurous pioneering spirit.
This OMEGA Speedmaster Professional “Moonwatch” features a black dial covered by a scratch-resistant sapphire crystal and graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. The black bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case and presented on a matching bracelet.
At the heart of this chronograph is OMEGA’s mechanical calibre 1863, the famous manual-winding movement worn on the Moon, visible through the transparent caseback.
Complicated watch with a function for measuring short time periods in addition to its function for permanently displaying hours, minutes and seconds.
