The legendary Speedmaster was the first - and still the only - watch to have been to the Moon. Originally designed to calculate speed with the chronograph and tachymeter functions on Earth, the 1957 Omega Speedmaster watch has proved time and time again an invaluable and life-saving partner to pilots and astronauts. With an impressive track record of six Moon landings, the Speedmaster has been on every US-manned space flight, making this manual-winding timepiece a cornerstone of horological and space history.
