Omega Moonphase Co-Axial Master Chronometer Moonphase Chronograph 44.25 mm Grey Dial (304.93.44.52.99.004)

Description

The Speedmaster is one of OMEGA’s most iconic timepieces, having been a part of all six lunar missions. Celebrating that history, this Moonphase model enhances the classic Speedmaster design with exquisite materials and precision.

The 44.25 mm case is made from platinum-gold, while the blue ceramic bezel ring includes a brushed platinum Liquidmetal™ tachymeter scale.

The sand-blasted platinum-gold dial is brought to life by its 18K white gold indexes that are set with baguette-cut diamonds. Complementing that colour is the blue ceramic moonphase disc at 6 o’clock that features two moons in platinum Liquidmetal™. The dial is completed by a magnified hand on the date subdial as well as blackened hours, minutes and central seconds hands all with white Super-LumiNova.

Presented on a blue leather strap, the timepiece is powered by the OMEGA Master Chronometer Calibre 9905, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (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 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).

• 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 case back

  A transparent case back – frequently made of sapphire – makes it possible to see the movement inside the watch.
