Omega SPEEDMASTER '57

CO‑AXIAL CHRONOMETER CHRONOGRAPH 41.5 MM

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 silvery dial with a seconds sub-dial at 9 o’clock and a 12-hour and 60-minute chronograph recorder on the sub-dial at 3 o’clock. There is a central chronograph seconds hand and a date window at the 6 o’clock position. A scratch-resistant sapphire crystal protects this bold dial. The 18K yellow gold bezel, with its tachymeter scale, is mounted on a 41.50 mm stainless steel casebody and presented on an 18K yellow gold and stainless steel 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.
