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 Speedmaster "Mark II" features an grey dial protected by a scratch-resistant sapphire crystal. There is a small seconds sub-dial at 9 o'clock, a 12-hour recorder at 6 o'clock and a 30-minute recorder at 3 o'clock, as well as a central hour, minute and fluorescent orange chronograph seconds hands. The transparent tachymeter scale on the sapphire crystal is illuminated from beneath by a fluorescent orange ring filled with Super-LumiNova.

The 42.40 mm stainless steel case is presented on a matching bracelet. At the heart of this chronograph is the exclusive  OMEGA Co-Axial calibre 3330.

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.

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.
