Omega’s watches have participated in many of mankind’s greatest adventures. Omega contributed genuinely pioneering achievements in the field of athletic time measurement at the beginning of the 20th century. And underwater too, Omega repeatedly astonished its competitors. Omega in specific and humankind in general experienced their most exciting moments neither at sporting events nor in the depths of the ocean, but in outer space: for example, some forty years ago, when the Speedmaster Professional accompanied the first men to land on the lunar surface. And today too, because the Speedmaster X-33 belongs among the standard equipment for all astronauts and cosmonauts.
