The OMEGA Speedmaster is one of OMEGAs most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brands adventurous pioneering spirit. This model features a silvery dial with a seconds sub-dial at 9 oclock and a 12-hour and 60-minute chronograph recorder on the sub-dial at 3 oclock. There is a central chronograph seconds hand and a date window at the 6 oclock position. A scratch-resistant sapphire crystal protects this bold dial. The brushed bezel, with its tachymeter scale, is mounted on a 41. 50 mm stainless steel case and presented on a matching bracelet. At the heart of this timepiece is the OMEGA Co-Axial calibre 9300, the first chronograph in the brands family of in-house Co-Axial mechanical movements.
