Strap colour: Silver
Case diameter: 43.00 mm

The Chronoscope collection has taken the legendary Speedmaster design and combined it with inspiration from OMEGA’s chronograph wristwatches from the 1940s. This 43 mm model is crafted in stainless steel with a silvery dial with blackened subdials. Along with a black anodized aluminium bezel ring with its tachymeter scale, the leaf-shaped hands and Arabic numerals are also blackened, with a unique “spiral” track pattern running beneath the numbers. Most notably, the dial is printed with three distinctive timing scales in a 1940’s “snail” design, including a tachymeter scale, a pulsometer scale and a telemeter scale. Presented on a stainless steel bracelet, the watch features a black small-seconds counter at 9H, and a black 60-minute and 12-hour recorder at 3H with red hands. Inside, the timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 9908.

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.
