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 OMEGA Speedmaster Professional “Moonwatch” features a black dial covered by a scratch-resistant sapphire crystal and graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. The black bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case and presented on a matching bracelet.

At the heart of this chronograph is OMEGA’s mechanical calibre 1863, the legendary manual-winding movement worn on the Moon, visible through the transparent caseback. This timepiece is offered with a special Moonwatch presentation box which contains a "NATO" strap, a strap for astronauts, a tool to change the bracelet and a book highlighting Speedmaster's adventures.

Stainless Steel

Stainless steel is certainly the most conventional of watchmaking materials for outer craftsmanship, and offers beauty, strength and affordability. OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.

Aluminium

Aluminium has the advantage of being a truly lightweight material used for decorative components. Through anodisation, it offers an extensive range of colours for the creation of eye-catching watch parts such as bezel rings, applied elements on the dial, and hands. In particular, OMEGA’s special anodisation process has achieved aluminium bezel rings that are nearly double as hard as regular versions, therefore making them more resistant to outer damage.

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.
