    Overview:  Omega introduced two major changes: the rhodium-plated 1863 caliber and the replacement of the tritium luminous paint for the dial indexes and the large hands by a non-radioactive substance called luminova.During a very short period, a transitional 3572.50 was produced with the new 1863 caliber and the tritium dial/hands. Many collectors consider it as the best of the two worlds: the more discrete rhodium-plated movement and the yellowish paint of the dial was produced in 1997 and is among the very last Speedmasters with tritium. It is in excellent condition.

    Launched in 1957 and designed to measure speed with chronograph and tachymeter functions, the Speedmaster has proved time and time again an invaluable and life saving partner to pilots, astronauts and explorers as they defy boundaries and push to ever-higher limits in the exploration of the universe. With an impressive track record of 11 NASA tests and 6 Moon landings, the Speedmaster has been on every US manned space flight and is currently on board Russia’s ISS International Space Station making this manual-winding timepiece a cornerstone of horological and space history.
