Omega Speedmaster Moonwatch Professional

The Omega Speedmaster Moonwatch Professional is one of the most recognizable mechanical chronograph watches in the Speedmaster collection. Its classic design combines a 42mm stainless steel case, black dial, three subdials and a tachymeter bezel.

The current Moonwatch Professional is powered by OMEGA’s Co-Axial Master Chronometer Calibre 3861, a manual-winding mechanical movement and modern evolution of the historic Calibre 321. OMEGA states that the movement provides Master Chronometer-certified precision, performance and magnetic resistance.

42mm Stainless Steel Case

The 42mm stainless steel case gives the Moonwatch its distinctive professional chronograph presence. Its balanced proportions preserve the traditional Speedmaster appearance while providing a strong everyday-wear profile.

Black Moonwatch Dial

The classic black dial features contrasting chronograph indications and a highly recognizable Speedmaster layout. The three-register configuration provides small seconds, chronograph minutes and chronograph hours.

Tachymeter Bezel

A defining feature of the Omega Speedmaster Moonwatch Professional is its tachymeter scale. Positioned around the bezel, the scale allows speed to be calculated over a measured distance.

Manual-Winding Calibre 3861

The watch is powered by the OMEGA Calibre 3861, a manual-winding Co-Axial Master Chronometer movement. The movement represents a modern development of the legendary Calibre 321 associated with the original Moonwatch era.

50-Meter Water Resistance

Official OMEGA documentation for the Moonwatch Professional lists 5 bar / 50 metres / 165 feet of water resistance.
