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 brushed five-arched-links-per-row bracelet, this 42 mm Moonwatch in stainless steel features hesalite glass on the front and an embossed Seahorse medallion on the caseback. Inspired by the 4th generation Speedmaster style worn on the moon, it also includes an asymmetrical case, black step dial and the famous dot over 90 on the 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.

The 4C's

The 4C's of a diamond are the four key characteristics that determine the quality and value of a diamond: cut, carat weight, color, and clarity. Together, these four characteristics are used to evaluate the quality and value of a diamond, and are considered when determining a diamond's price.

Carat Weight

Carat weight is a unit measurement used for a diamonds weight, where 1 carat = 0.2 grams. Points can also be used whereby 1 carat = 100 points. Because larger diamonds are rarer, they generally have a higher price per carat.

Cut

The cut of a diamond equals the overall shape of the stone. A good diamond worker can cut a diamond in almost every shape imaginable. In the end the shape of a diamond you select is a matter of personal preference.

Clarity

Clarity equals the purity of a diamond,this can vary from flawless (zero imperfections) to blemishes (a lot of imperfections). These imperfections, like fractures, are tiny parts of carbon or air bubbles. A natural diamond is rarely without perfections.

Color

The color of a diamond relates directly to a diamond’s value. This color can vary a lot, from white to yellow/brown. The diamond’s color can be graded from a scale that begins with D, then progress down the alphabet with each letter designating.
