[product_description]The Speedmaster Moonwatch is one of the world’s most iconic timepieces. Having been a part of all six moon landings, the legendary chronograph is an impressive representation of the brand’s adventurous pioneering spirit. Presented on a polished-brushed bracelet, this 42 mm Moonwatch in stainless steel features sapphire crystal glass on the front as well as on the caseback. Inspired by the 4th generation Speedmaster style worn on the moon, it also includes an asymmetrical case, a white lacquered step dial with applied OMEGA logo and indexes, Moonwatch style hands, and the famous dot over 90 on the black anodised aluminium bezel ring. The watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 3861, which powers the small seconds sub-dial, 30-minute recorder and 12-hour recorder, along with the central chronograph function.[/product_description]

Anti-Magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).

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).

Transparent Caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.

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.

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.

Unidirectional Rotating Bezel: A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.

Bi-Directional Rotating Bezel: A bezel which can be turned clockwise or anti-clockwise. Rotating bezels can be used to time events, measure elapsed times, or read second or third time zones.

Diamonds: The hardest, most luminous precious stone whose value is calculated according to the 4C criteria: Cut - Carat - Clarity - Color.

Numbered Edition: A watch series each of whose pieces is numbered sequentially in the order it is produced.

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.

Pulsometer: Pulsometer A watch with a scale to measure the number of heartbeats per minute.

Telemeter: This precision tool can measure exactly how far you are from something that is visible and audible, such as your distance from a lightening storm.
