Omega watches in space exploration

The Omega Speedmaster, or "Moonwatch", selected by NASA for all the Apollo missions

Omega Speedmaster Professional

The selection of the "Omega Speedmaster Professional Chronograph" for American astronauts was the subject of a rivalry between Omega and Bulova.

All subsequent manned NASA missions also used this handwound wristwatch. NASA started selecting the chronograph in the early 60s and automatic chronograph wristwatches were not available until 1969.

However all the instrument panel clocks and time-keeping mechanisms in the spacecraft on those space missions were Bulova Accutrons with tuning fork movements,[citation needed] because at the time NASA did not know how well a mechanical movement would work in zero gravity.

First watch on the moon

The "Omega Speedmaster Professional Chronograph" was the first watch on the moon, worn by Neil Armstrong and Buzz Aldrin. Armstrong's watch is now displayed at the National Air and Space Museum in Washington D.C.

Aldrin's is believed lost. He mentions in his book, Return to Earth, that when donating several items to the Smithsonian Institution, his Omega was one of the few things that was stolen from his personal effects.

In 2007, to mark the 50th anniversary of the Omega Speedmaster Professional Chronograph, the Omega company unveiled the commemorative Speedmaster Professional Chronograph Moonwatch. The watch had the distinctive features of the first hand-winding Omega Speedmaster introduced in 1957. It was sold in an edition of 5,957.
