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 black rubber strap. 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.
