This OMEGA Speedmaster Professional “Moonwatch” features a black dial covered by a scratch-resistant sapphire crystal and graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. The black bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case and presented on a black leather strap.  At the heart of this chronograph is OMEGA’s mechanical calibre 1863, a descendent of the legendary manual-winding movement worn on the Moon, visible through the transparent caseback. This timepiece is offered with a special Moonwatch presentation box which contains a "NATO" strap, a strap for astronauts, a tool to change the bracelet and a book highlighting Speedmaster's adventures.
