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 HB-SIA Co-Axial GMT Chronograph honours the Solar Impulse project and its aim to fly around the globe powered only by energy from the sun. It features a black carbon fibre dial graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with central chronograph and GMT hands.

The black bezel, with its tachymetric scale, is mounted on a 44.25 mm titanium case and presented on a titanium bracelet. At the heart of this numbered edition timepiece is the Co-Axial calibre 3603. Etched on the caseback is the patch of the Solar Impulse HB-SIA project.

Key materials

  • Material - Grade 2 Titanium

    Grade 2 Titanium

  • Material - Sapphire Crystal

    Sapphire Crystal

Grade 2 Titanium

Titanium alloys are light, corrosion-resistant, biochemically inert and able to withstand extreme temperatures. These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors. They achieve the perfect balance between solidity, corrosion-resistance and workability. Grade 2 titanium offers a dim grey colour and suits mostly "brushed" finished pieces. It has featured in a number of OMEGA timepieces used for sport and space exploration, where light reflections should be avoided.

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.

The advantages
of this watch

At the heart of this timepiece is the Co-Axial escapement, a revolution in watchmaking when first introduced. The reduced stress on the moving parts means less need for lubrication, longer-lasting accuracy and a more stable power reserve rate. In short, this timepiece performs better for longer.
