Collection Item Summary:

Harrison Schmitt, the only scientist-astronaut to go to the Moon, wore this chronograph during the Apollo 17 mission. The Omega Speedmaster Chronograph was chosen by NASA for the U.S. space program after a series of rigorous tests demonstrated its high level of precision and reliability. Program requirements called for a manual-winding wrist chronograph that was water-proof, shock-proof, anti-magnetic, and able to withstand temperatures ranging from 0 to 200 degrees Farenheit and accelerations of 12 g's. The Omega Speedmaster was certified by NASA as the chronograph for the Gemini program in June 1965, and was also purchased for all programs that followed through today.

NASA transferred the chronographs to the Museum in 1977.
