Omega Speedmaster Moonphase Co-Axial Master Chronometer Chronograph Mens Watch O30433445203001

The Speedmaster is one of OMEGA’s most iconic timepieces, having been a part of all six lunar missions. Taking the spirit of exploration a step further, this new Moonphase features two infinitely small yet photo-realistic moons.

This 44.25 mm model features a blue sun-brushed dial, with rhodium-plated indexes. At 6 o'clock is the accurate Moonphase indication, which features a metallic crystal disc microstructured to obtain a high resolution image of the moon.

The stainless steel case is complemented by a blue ceramic bezel ring with Liquidmetal™ tachymeter scale and presented on a blue leather strap with a polished-brushed foldover clasp.

Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9904, 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).

Automatic Watch: A self-winding watch or automatic watch uses a mechanical movement whose main spring is wound automatically by the natural motion of the wearer's arm.

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).

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 Case Back: A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
