Omega Speedmaster Moonwatch Professional Ref. 311.33.42.30.01.001

Omega Speedmaster Moonwatch Professional

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 hesalite 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 1861, a descendent of the legendary manual-winding movement worn on the Moon. 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.
