Omega - Speedmaster Moonwatch Professional Chronograph - 311.30.42.30.01.006 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 OMEGA Speedmaster Professional “Moonwatch” features a black dial covered by a scratch-resistant sapphire crystal and graced by a small second 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 matching bracelet. At the heart of this chronograph is OMEGA’s mechanical caliber 1863, a descendent of the legendary manual-winding movement worn on the Moon, visible through the transparent case back.
