Speedmaster Moonwatch Professional 42 mm

The Speedmaster Moonwatch is one of the world’s most iconic timepieces.
Having been a part of all six moon landings, the legendary chronograph is an impressive representation of the brand’s pioneering spirit.

Inspired by the 4th generation Speedmaster, this 42 mm Moonwatch in 18K Moonshine™ Gold, has a sun-brushed 18K Moonshine™ Gold "step" dial with blackened subdials and indexes. The black ceramic bezel ring, with OMEGA Ceragold™ tachymeter scale, features the famous dot over 90. As a tribute to its history, the underside of the integrated black rubber strap has a lunar surface pattern in positive relief.

The caseback in polished 18K Moonshine™ Gold has double bevels and the words FIRST WATCH WORN ON THE MOON engraved in black. The Moonwatch is powered by OMEGA's Co-Axial Master Chronometer Calibre 3861 with special luxury finish.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronograph: The chronograph function is a mechanism for measuring time intervals. A chronograph watch can therefore be used to time events while displaying the time like any traditional watch.
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Small seconds: A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.
Tachymeter: A tachymeter watch has a function for measuring speed. It is a chronograph with a graduated dial on which speed can be read in kilometres per hour based on a 1000 metre distance.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
