OMEGA Speedmaster '57 Co-Axial Master Chronometer Chronograph 40.5mm O33210415101001

The Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the timepiece is an impressive representation of the brand’s adventurous pioneering spirit. This 40.50 mm model, inspired by the legendary 1957 original, features a stainless steel case and a black dial with recessed hour markers showing vintage Super-LumiNova from beneath. Along with rhodium-plated “Broad Arrow” hands, there is a date window at 6 o'clock, a small seconds subdial at 9 o’clock, and 12-hour and 60-minute chronograph recorders on the subdial at 3 o’clock. The brushed bezel includes a blackened tachymeter scale, while on the caseback, there is a “Speedmaster ‘57” engraving as well as a flat sapphire crystal with an anti-reflective treatment inside. The watch is presented on a matching bracelet with OMEGA’s patented comfort release adjustment system, and is driven by the manual-winding OMEGA Co-Axial Master Chronometer Calibre 9906.

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.
