Omega Speedmaster '57 Co‑Axial Chronometer Chronograph 18K RG & SS 41.5mm Black Dial
331.20.42.51.01.002
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 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 red gold bezel, with its tachymeter scale, is mounted on a 41.50 mm stainless steel casebody and presented on a 18K red 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.
