The most famous The aerial clock is undoubtedly the Omega Speedmaster. The most famous, in fact, is one of the few clocks that enjoys real-time recognition than aficionados.
What is not clear is the dangerous test that NASA put in the original 321 Speedmaster. At the start of its Gemini mission in 1961, NASA realized that astronauts needed a clock that could withstand the extreme heat and g-energy that occurs during flight. Thus, in October 1964, mechanical watchmakers were approached and asked to donate watches that they thought could work in space. Only four brands were brave enough to heed the call: Hamilton, Rolex, Longines, and Omega.
NASA immediately canceled Hamilton’s entry. Surprisingly, the company offered a wristwatch instead of a pocket watch. The space agency put the records of Rolex, Longines, and Omega through 11 tests designed to measure the position of the atmosphere and the month.
These rigorous tests included spending 48 hours at 70 ° C then 30 minutes at 93 ° C, then four hours at -18 ° C; fifteen 45 minutes around 71 ° C and -18 ° C; acceleration from standing to 7.25 g’s within 5 minutes, then 16 g for 30 seconds, along with three axes; vibration from 5 to 2,000 Hz along three axes, with a velocity of at least 8.8 g’s; and decompression for 90 minutes about vacuum at 10-6 in the air.
Rolex and Longines both failed in the hottest tests, but Omega went on to test all 11 tests, and was awarded a NASA certificate. Ideally, then it makes up our list below for a select group of five clocks related to air travel.
