Speedmaster Moonwatch OMEGA Co-Axial Chronograph

From the retailer listing

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 features a black dial graced by a small 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 black bezel, with its tachymetric scale, is mounted on a 44.25 mm stainless steel case and presented on a 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
