In 1964, Deke Slayton, Director of Flight Crew Operations at NASA's Space Program Office, selected four aviation chronographs from 10 famous brands and sent them to James Ragan, an engineer for aerospace engineering programs, for testing. Ragan first eliminated one of the watches because it was not a watch. The remaining three watches underwent 11 rigorous tests, including high temperature, low temperature, temperature pressure, relative humidity, pure oxygen environment, shock, acceleration, decompression, low pressure, vibration, and noise, for half a year from September 1964 to March 1965, to evaluate their actual operating capabilities under harsh environmental conditions.
Such tests are even a bit too harsh for watch products, such as the high temperature test: the watch needs to be exposed to 70 degrees Celsius for 48 consecutive hours, and then it needs to withstand a high temperature of 93 degrees Celsius for 30 minutes in a partial vacuum environment. It was during this stage of the thermal vacuum test that the watches of the two brands failed one after another and failed to pass the test. During this period, the second hand of a certain watch was deformed during humidity and high pressure tests, and the watch mirror of another watch fell off during pressure tests. Only Omega's Speedmaster Ref. 105.003 successfully passed all 11 tests and successfully passed NASA certification. On March 1, 1965, it was announced by the National Aeronautics and Space Administration (NASA) as "approved to participate in all its manned space flight missions."
