Speedmaster Moonphase 44.25 mm

The Speedmaster is one of OMEGA’s most iconic timepieces, having been a part of all six lunar missions. Celebrating that history, this "Blue Side of the Moon" model takes its name from the colour of the dark blue sky.The 44.25 mm chronograph features a blue ceramic case complemented by a blue ceramic bezel ring with an OMEGA Ceragold™ tachymeter scale. It is presented on a blue leather strap with a blue ceramic and ceramised titanium foldover clasp.Most vividly, the dial is blue aventurine glass and includes 18K Sedna™ gold indexes and hands as well as a date hand with red tip. At 6 o'clock is the accurate Moonphase indication, which features a blue enamel aventurine glass Moonphase disc (patent pending) with near and far sides of the moon in Sedna™ gold.Powering the timepiece is the OMEGA Master Chronometer Calibre 9904, 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 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).
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.
