Really great watch!

It's a really nice watch that looks even better in person. I especially like the simplicity with no date and no extra second hand. A very clean, beautiful design! At first I was worried if I would like the textured dial, but it's just perfect!

EPSON YM90A MOVEMENT

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

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 meets the CNES standards and will be equipped by a chronometer which allows the user to perfectly situate himself/herself in the parabolic time-space. More precisely said, in the rhythmic pace of the trajectories that follow every 3 minutes, especially between 22 seconds and 44 seconds (Zero-G stages). This timepiece gathers every aspect of this demanding activity that I love. As a civil pilot, I love the precision and fluidity aerial trajectory. Being passionate about space and science, I am pleased to have helped YEMA in designing this watch which will offer technology in contributing to the benefit of science. "
