YEMA's latest French moonwatch designed in collaboration with France’s Space Agency commemorate the 30th anniversary of French parabolic flights (simulated gravity). Designed to meet the strict requirements of ZERO-G flights' crew members, this new Spacegraf combines perfect readability at all times with high precision. The chronograph feature allows precise reading of G periods during parabolic flights and easiness-of-use when in weightlessness.
The Spacegraf ZERO-G 316 L stainless steel case is treated with PVD, a high quality coating known by its inalterability, hardness and excellent resistance to corrosion and scratches
In combination with the chronograph function, the tachymeter bezel allows measuring of airspeed, flight time and distance of parabolic flights
The aviator-style hands and the oversized applied markers are treated with Super-LumiNova C1 to ensure perfect readability during parabolic flights
The Spacegraf ZERO-G dial subtle difference in height and texture inspires from the lunar surface
The caseback is engraved with France's Space Agency (CNES) official logo and markings to commemorate both the 30th anniversary of parabolic flights and YEMA's First French Watch Sent Into Space
The Spacegraf ZERO-G's canvas strap has been specifically designed to withstand extreme in-flight conditions when in microgravity but also to be worn elegantly with a dressier outfit
The hands and markers are coated with Super-LumiNova C1 so as to secure perfect readability in the dark
Les aiguilles et les index sont revêtus de Super-LumiNova. La Superman héritage Blue offre donc une parfaite lisibilité dans l'obscurité.
Precise time measurement and high accuracy (to the nearest second) is a highly sensitive matter for astronauts. France's Space Agency has privileged a quartz movement over a mechanical one so as to ensure high precision at all times and under all extreme conditions of parabolic flights. During flight tests, the Epson YM90 movement managed to meet all these requirements by perfectly timing zero G periods (chronograph function in combination with red highlighted seconds markers) and parabolic flight stages (minute chronograph feature at 6 o’clock).
Parabolic flights (or zero G flights) are a gateway to weightlessness. They are dedicated to scientific experiments and to space equipment technological testing. From a flight attitude at 24,000 feet, the ZERO-G aircraft increases attitude. During this phase, the weight is 1.8 times greater than normal weight for 22 seconds. Then the aircraft trajectory is piloted to follow a kind of parabola and the power thrust is reduced. The vertical load factor goes from 1.8G to zero gravity for about 22 seconds. The first pilot adjusts the control stick tilt to maintain the vertical load factor at zero, while the second pilot maintains the roll angle at zero, and the mechanic adjusts the thrust of the engines to cancel the longitudinal load factor. An exit phase at 1.8G symmetrical with the entry phase, is then performed on the descending part of the parabola to return the aircraft to a stabilized altitude level within 22 seconds.

" This chronograph perfectly meets CNES standards and requirements. It is equipped by a chronometer which allows crew members to perfectly situate themselves in time/space during parabolic flights by anticipating the 22 seconds zero G stages that follow every 3 minutes. This timepiece gathers every aspect of this extraordinary demanding activity that I love. As a civil pilot, I come to appreciate the beauty and precision of aerial trajectories. Being passionate about space and science, I am pleased to collaborate with YEMA in designing this space chronograph while contributing to the benefit of science. "

YEMA's signature #TimeofHeroes dates from 1970. It reflects the history and values of the brand and what it stands for. It tells the adventures of remarkable sportsmen and explorers who have achieved the extraordinary under the most extreme conditions, with a YEMA watch on their wrists.
Designed in 1982 in collaboration with France's Space Agency (CNES), the YEMA Spationaute was the first French and Western European watch sent into space. It was worn by Jean-Loup Chrétien during the French-Russian mission PVH, Soyouz T-6.
The CNES is responsible for the development and implementation of France's Space Program. CNES is the most important National Space Agency after NASA.
