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 “ Moonphase” Chronograph features a black dial graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. A fourth sub-dial, at the 12’clock position, has moonphase and date indicators.
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 timepiece is OMEGA’s mechanical calibre 1866, visible through the transparent caseback.
A moonphase watch uses a function which tracks the phases of the moon. One lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds and includes four phases: new moon, first quarter, full moon, last quarter.
A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.

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.

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.
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.
