Description

The OMEGA Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand’s adventurous pioneering spirit.

This model features a black enamel dial graced by a small seconds sub-dial at 9 o’clock and a 12-hour and 60-minute chronograph recorder on the sub-dial at 3 o’clock. There is a central chronograph seconds hand and a date window at the 6 o’clock position. A scratch-resistant sapphire crystal protects this bold dial. The black ceramic bezel, with its tachymetric scale, is mounted on a 44.25 mm 18K orange gold case and presented on a black leather strap. At the heart of this timepiece is the OMEGA Co-Axial calibre 9301, the first chronograph in the brand’s family of in-house Co-Axial mechanical movements.

Key materials

Material - Sapphire Crystal

Sapphire Crystal

Sapphire Crystal

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.

A new look for your watch

Your watch and strap should go together perfectly, but that doesn't mean you can't experiment with different combinations. Why not mix things up and see what happens? You may discover a look that's as individual as you are.
