After that, watch this manufacturer used by astronauts over half a century, they are used now. Only now in the cosmos has been working model Speedmaster Skywalker X-33.

Omega developers actively working with the astronauts, trying to get feedback about their hours, to create a new, more efficient model. One of the volunteers, who agreed to test watches Omega, became astronaut ESA Jean-François Clervoy , who spent 675 hours in space.

It was his submission in hours for astronauts, two new functions: MET (Mission Elapsed Time, mission elapsed time), and PET (elapsed time of a separate phase, phase elapsed time). For different tasks can put astronaut Service (sound events) with individual tone sound. After a little practice, it helps to understand what the mission is complete, and what - is yet to be.

There are also digital LCD display, as well as analog dial with illuminated figures, making it easy to see the information in complete darkness.

Each new model of watch for astronauts tested on our own test site in the Netherlands. In addition, the clock in the centrifuge test, where the mechanism is exposed to accelerations in excess of 7 times the load of the earth. Simulator used and shaking, vibration, which emulates the vibration of the spacecraft during launch.
