OMEGA is proud to include the Swiss Made mark on all of its watches. This simple wording guarantees a standard of quality established over many centuries and is a world-renowned symbol of excellence.
Having been a part of all six lunar missions, the legendary OMEGA Speedmaster is one of the world’s most iconic timepieces. This model has reprised the famous Calibre 321, which was an important part of the Speedmaster’s original space history.
The 39.70 mm case is in stainless steel and is inspired by the same 3rd generation style worn during America’s first spacewalk in 1965. There is also a bezel ring in polished black ceramic [ZrO2] with the tachymeter scale in white enamel.
The black step dial features familiar Moonwatch hands, a vintage OMEGA logo, as well as a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. Through the sapphire-crystal caseback, you can see the Calibre 321 inside.
Chronograph
The chronograph function is a mechanism for measuring time intervals. A chronograph watch can therefore be used to time events while displaying the time like any traditional watch.
Small seconds
A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.
Tachymeter
A tachymeter watch has a function for measuring speed. It is a chronograph with a graduated dial on which speed can be read in kilometres per hour based on a 1000 metre distance.
Transparent caseback
A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.

Key materials
Stainless Steel
Sapphire Crystal

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.

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.
