As well as beautifully measuring every moment on earth; this timepiece follows the phases of the moon, which makes perfect sense given that the Speedmaster was the first watch ever to be worn on the lunar surface. As a Master Chronometer, the Moonphase celebrates another pioneering moment: OMEGA's exacting new standard of testing approved by METAS in 2015.
A bold use of blue gives the Moonphase its distinctive look. The sun brushed dial, ceramic bezel and leather strap are all in brilliant blue. The case is in stainless steel and the twin two-handed subdials with rhodium-plated circles give the watch a beautifully symmetrical look. The image of the moon, in sharply contrasting black and white, is as detailed as a NASA photograph.
"…Liquidmetal® has been used on the tachymeter scale, which is another Speedmaster first…"
A brief astronomy lesson: a lunar month is not 30 days, but slightly more than 29.5 days. A difficult time-span to manage for a standard gear train, but OMEGA's Moonphase is up to the task. Its highly accurate mechanism only needs adjusting after 10 years, and all it takes is a few turns of the crown.
The revolutionary new 9904 movement is made up of 368 components and marks the start of a whole new era in watchmaking: the Co-Axial Master Chronometer has landed.
"… a Master Chronometer is a movement tested at the industry's highest level… "
Avant-première at Baselworld, available in stores in October 2016
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Complicated watch with a function for measuring short time periods in addition to its function for permanently displaying hours, minutes and seconds.
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
The day of the month, displayed in a window on a watch dial typically at the 3 o'clock or 6 o'clock position.
Liquidmetal is an alloy which is considerably harder than stainless steel yet bonds seamlessly with ceramics. The blended materials are particularly resistant to scratching and corrosion.
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.
A hand on a sub-dial which tracks seconds; typically it completes a full rotation in one minute.
A tachymeter is an instrument for measuring speed. It is a chronograph with a graduated dial on which speed can be read off in kilometres per hour based on 1000 metres distance.
