The story of arguably the most impactful competition in horological history has now passed into legend.
In 1965, NASA put out the call for a watch that could withstand the rigors of space travel and meet its exacting timekeeping standards.
The field was narrowed down to three chronographs: an Omega Speedmaster reference ST105.003, a Wittnauer 235T and a Rolex reference 6238 proto-Daytona.

NASA put the watches through 11 tests to measure performance under extremes in pressure, temperature, sound, humidity, vibration, corrosion and shock absorption, along with performance in a vacuum.
Only one watch passed all the tests and received a contract to be the official wristwatch of the American space agency.
As we are all acutely aware, it was the Speedmaster, and Omega has proudly flaunted the “First Watch on the Moon” badge ever since.
