The Speedmaster is one of OMEGA’s most iconic timepieces, having been a part of all six lunar missions. With its two moons made from genuine moon meteorite, this 43.00 mm Moonphase watch is a striking tribute to that distinguished legacy.

Its dial, a PVD black-coated meteorite plate, features hour/minute hands and indexes in 18K white gold. The hands on the two black-coated subdials are also in 18K white gold.

At 6 o’clock is the unique Moonphase display, with north and south hemisphere indications, and two moons, made from shaped, polished and domed lunar meteorite which fell to Earth.

The case in polished-brushed stainless steel is complemented by a polished black ceramic bezel ring with white enamel tachymeter scale. Fixing the Moonphase watch to the wrist is a bracelet in polished-brushed stainless steel. With patented comfort release adjustment as used on the famous Speedmaster.

Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9914 manual winding chronograph calibre, which has been officially certified by METAS.

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 been successfully tested by an accredited and independent laboratory in order to receive a certificate compliant with the chronometer ISO 3159 standard.
Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
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).
Moonphase: A moonphase watch uses a function which tracks the phases of the moon. One lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds and includes four phases: new moon, first quarter, full moon, last quarter.
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.
