Moonwatch Professional 42mm Steel on steel Hesalite

For well over half a century, the OMEGA Speedmaster has been at the heart of those great moments in time that tested the limits of physical endurance and human courage, including the first manned lunar landing in July of 1969 and, every single one of NASA’s manned missions since March of 1965.

The world’s most famous chronograph
The OMEGA Speedmaster Professional Chronograph has a unique place in the history of space exploration as the only piece of equipment to have been used in all of NASA's manned space programs from Gemini in the mid-1960's to the current International Space Station program. Even before its official approval, it had been the private choice of astronauts on two of the one-man Mercury missions.

Earning a nickname: "We choose to go to the moon ..."
President John F. Kennedy’s challenge to send an astronaut on the Moon was particularly audacious considering that when he first voiced it, only one American had been in space for a grand total of 15 minutes and 28 seconds.When Buzz Aldrin stepped onto the lunar surface in July of 1969, the OMEGA Speedmaster Professional earned its distinctive nickname, The Moonwatch.

Like no other chronograph
Speedmaster was designed to stand apart from other chronographs. A black dial, luminous hands, tachometer scale, water-resistant case, screw-in back, domed crystal and an additional inner cover to protect the movement incorporate the strong character of an instrument watch. The characteristic Speedmaster dial has minute and hour chronograph counters which are complemented by a third sub-dial for the small seconds. The central chronograph seconds hand is activated and stopped by the top pusher on the side of the watch and reset with the bottom one.
