Limited Edition of 1,924 Pieces The ESA-qualified timepiece commemorates OMEGA's pioneering spirit and its relationship with Solar Impulse, just in time for it's long awaited round-the-world journey. More than a remarkable timepiece, the Speedmaster Skywalker X-33 Solar Impulse Limited Edition is a celebration of a project whose ambitious aim is to circle the globe in an airplane powered only by solar energy, making a bold statement about viable alternatives to non-renewable energy. Technical Specifications: The case, in grade 2 titanium, measures 45mm. It has a blue ceramic bezel coated with white SuperLuminova, an AR-coated sapphire crystal, and it is water resistant to 30 meters. The caseback is secured with eight screws and is stamped with the Solar Impulse "Around the World" patch and engraved with the name of the timepiece as well as the words "TESTED AND QUALIFIED BY ESA" (European Space Agency). Movement is the Swiss quartz Omega caliber 5619 with a thermo-compensated integrated circuit. In addition to its analogue and digital displays, this timepiece has two functions that will prove useful for the pilots: mission elapsed time (MET) and phase elapsed time (PET). The dial is blue and green, with white transferred indeces and SuperLuminova-coated hour markers. The LCD display is grey on a black background, and shows the hour, minutes and seconds of up to three different time zones, three alarms, chronograph and countdown functions, and a perpetual calendar with day, date, month, year and week number indications. The hands are skeletonised black and white, coated with SuperLuminova (green light emission), with a black and green central seconds hand. The hands can be disengaged to allow clear reading of the digital display. It comes on a new blue and green-bordered polyamide "NATO" strap with titanium keepers and buckle. It will be produced in an edition limited to 1,924 pieces. The number honors the year that the first round-the-world flight took place; members of the United States Army Air Service flew around the world from 4 April to 28 September 1924.
