OMEGA SPEEDMASTER '57 CO-AXIAL CHRONOGRAPH 41.5 MM steel on steel Ref. 331.10.42.51.01.002

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 model, inspired by its legendary predecessor, features a black dial with beige transferred dial indications. There is a small seconds sub-dial at 9 o'clock and a 12-hour and 60-minute chronograph recorders on the sub-dial at 3 o'clock.

The hour markers are recessed and partially filled with Super-LumiNova that emits a green light. The polished facetted rhodium-plated central hour and minute hands have been created in the "Broad Arrow" style and are coated with Super-LumiNova.

The 41.5 mm stainless steel case is presented on a matching bracelet. At the heart of this timepiece is the OMEGA Co-Axial calibre 9300, the first chronograph in the brand's family of in-house Co-Axial mechanical movements.
