The Omega Speedmaster Professional is by far one of our most favorite chronographs. The Speedmaster has an incredible history starting with automotive racing moving into flight and eventually to NASA and the U.S. Space Program.  There are many subtle differences within the vintage Omega Speedmaster range of references that make them all slightly unique and different.

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 matching bracelet. At the heart of this chronograph is OMEGA’s mechanical calibre 1863, the famous manual-winding movement visible through the transparent caseback.
