Elon Musk's SpaceX made history on Saturday May 30, with the inaugural launch of two NASA astronauts into orbit aboard a private company spacecraft.

The last US-registered flight dates back toJuly 8 2011 when it was launched Space Shuttle Endeavor from US soil. It was the twenty-fifth mission in space for the United States of America and thanks to a private, Elon MuskNASA come back with the mission demo-2.

The Crew Dragon with astronauts on board Bob Behnken e Doug Hurley, took off from the Kennedy Space Center in Florida at 15:23 pm aboard a rocket F for its 19-hour trip to the International Space Station (ISS), the first human spaceflight from American soil since 2011.

While following the exciting live broadcast, the most attentive observers will have noticed a watch that has written the history of space travel and that has found its second home in space. We're talking about Omega Speedmaster. On board the Crew Dragon, on the wrist of veteran Bob Behnken there is in fact a Omega Speedmaster X33.

In March 1965, the history of watchmaking was made when the program of the NASA Qualification Test Procedures decided that theOmega Speedmaster it would be the watch that would accompany the American astronauts on their trip to the moon. After proving its reliability and durability during the first lunar mission, the iconic Speedmaster it was used by astronauts around the world for decades to come, until 1995, when it was decided that a specially designed upgrade was due.

After a series of prototypes were tested and developed in collaboration with a number of astronauts and pilots, and the watch proved itself in many respects, Omega officially launched Speedmaster Professional X-33 “Mars Watch” in 1998 through a live satellite presentation of the clock aboard the Russian Mir space station.

In order to ensure that the watch was able to function according to these standards, Omega invited highly trained professionals such as the commander Tom Stafford (Apollo-Soyuz Test Project, Apollo 10 and Project Gemini) and notable figures from squadrons such as the Blue Angels and Thunderbirds to provide thoughtful input.

With their help, a series of prototypes of the X-33 were created over the course of three years and tested by Russian cosmonauts including Victor Afansiev and the NASA astronaut Richard Linnehan, to name just two. This effort by the team to develop the X-33 makes the watch even more exciting, as it is the product of the brightest minds in aerospace engineering and watchmaking.
