OMEGA Speedmaster GMT “Solar Impulse”

Launched in 2008, the OMEGA Speedmaster GMT “Solar Impulse” was inspired by and created in honour of the Solar Impulse project whose ambition was to circumnavigate the globe in an airplane powered only by the sun.

The watch combines elegant but sporty design with cutting-edge technology. Its dramatic, Speedmaster-influenced dial is made of black carbon fibre similar to the HB-SIA’s composite covering. The slightly-recessed black chronograph and small seconds counters creatively contribute to the watch’s outstanding legibility. Another detail on the timepiece’s unique dial is the discreet “HB-SIA” appearing in ochre on the dial at 12 o’clock.

The Speedmaster GMT “Solar Impulse” features central hour, minute hand, and chronograph seconds hand. There is also a central GMT hand, with an airplane-shaped pointer, which completes one rotation in 24 hours and can be used to read a second time zone.

The GMT hand can also be used for compass orientation: When the watch’s hour hand is pointed in the direction of the sun, the GMT hand, when it is adjusted to the same time on the 24-hour GMT scale, will indicate north. The titanium bezel is fixed with a matte black aluminium ring and features the designation “TACHYMETER BASE 1000” in ochre with a tachymeter index.

The 44.25 mm case is fashioned of brushed, polished titanium and is presented either on a matching titanium bracelet or a rubber strap designed especially for the watch. The distinctive, textured finish on the inside of the rubber strap is reminiscent of the Solar Impulse’s carbon fibre-honeycomb composite structure.

The Speedmaster GMT “Solar Impulse” is a numbered edition and its number is engraved on the caseback which also features a colourful, etched Solar Impulse HB-SIA patch. The watch is powered by the exclusive Omega Calibre 3603 whose revolutionary Co-Axial Escapement and free sprung balance deliver stable long-term accuracy and reliability and is a COSC-certified chronometer. It is equipped with a sophisticated column-wheel chronograph mechanism.
