The first watch to be worn on the moon is the Omega Speed­mas­ter Pro­fes­sional. Nick­named the Moon­watch, it was the timepiece that recorded man’s first steps on the moon on July 21, 1969, on the Apollo 11 mis­sion, and was part of all six manned lu­nar land­ings from 1969 to 1972. This spaceage ac­ces­sory has with­stood con­di­tions of zero grav­ity and mag­netic fields, ex­treme shocks, vi­bra­tions and tem­per­a­tures rang­ing from mi­nus 18 to 93 deg C. To­day, the up­dated Speed­mas­ter X-33 is flight-qual­i­fied by the National Aero­nau­tics and Space Ad­min­is­tra­tion (Nasa) and the Rus­sian space agency, and is a stan­dard piece of equip­ment for as­tro­nauts.
