The Speedmaster reference ST 105.003 submitted by Omega was the only watch to pass every test, with the Longines and Rolex both failing during the high-temperature test.
Separately, Ragan gave all of the watches to astronauts to evaluate on their own without informing them of the test results. The astronauts unanimously chose the Speedmaster, clearing the path for Ragan to recommend the Omega for missions.
As a result, the Speedmaster Professional was the sole watch to earn NASA’s qualifications for manned space flight and extravehicular activity, and the rest, as they say, is history.

When visiting Omega, it’s impossible to miss the importance of the brand’s connection to NASA and space exploration. A life-sized lunar lander replica greets you in front of the brand’s headquarters, and the most elaborate section of the fascinating on-site museum is dedicated to the Speedmaster and space travel.
During my visit, my colleagues and I were presented with some incredible watches that told the story of Omega’s, and America’s, history in space.
