Watches & Pencils #21 - The NASA Tests along with the SpeedmasterThis episode we finally set the Speedmaster watch the center of attention of the Watches & Pencils feature. Specifically, we focus within the first Speedmaster that's passed the NASA tests: the Omega Speedmaster with regard number 105.003. Generally known as the 'Ed White' Speedmaster. At a later date a little more about the NASA tests panerai radiomir gmt watches :Form and Function Surrender HandThe thing that really fascinates me relating to this watch is the fact there's this kind of harmony between form and function. Basic principles from the Speedmaster are rock solid right from the start; As you move the watch passed the many NASA tests, it was never designed specifically for the tests. Before the 105.003 the watch was a commercial watch like all other. A sports chronograph. This became also confirmed by Jim Ragan, the NASA engineer who tested the Speedmaster. Though, the truth that astronauts bought Speedmasters privately (Schirra, Cooper and Slayton) for use at NASA prior to certification did show the potential.Archive picture of Jim Ragan testing a Speedmaster.

It is usually named 'Ed White' as they was the first astronaut who achieved a space walk throughout the fourth Gemini mission. Although the Speedmaser 105 .003 was the initial NASA certified watch, it would not be named Moonwatch; no Gemini mission designed a day at the moon. The Gemini objective ended up being to develop space travel methods to support Apollo's pursuit to land astronauts within the Moon. We all know, replica rolex at a later date, the Apollo program plus the Speedmaster 105.012ST turned the Speedmaster (Professional) to the Moonwatch.Gemini IV patch. The mission where Edward H. White achieved the first EVA (extravehicular activity) or space walk.105.003-65 (auctioned at Christie's)NASA TestsAfter a lengthy and intensive test period the Speedmaster took over as exclusive wristwatch for astronauts in 1965. What tests did the 105.003 (or NASA reference 6049 - USA designation) pass?High temperature test: 70 C for 2 days, then 93 C for Thirty minutes within a partial vacuum.Cold test: -18 C for 4 hours.Vacuum test: heated inside a vacuum chamber after which cooled to -18 C for a number of cycles.Humidity test: ten 24-hour cycles in >95% humidity with temperatures including 25 C to 70 C.Corrosion test: in a atmosphere of oxygen at 70 C for A couple of days.Shock-resistance test: six 40 G shocks in six different directions.Acceleration test: progressive acceleration to 7.25 G for approximately 铿乿e minutes then to 16 G for Half a minute in three axes.Low pressure test: pressure of 10'6 atmospheres at 70 C for 90 minutes, then at 93 C for Thirty minutes.Underhand test: in an air pressure of a single.6 atmospheres for Sixty minutes.Vibration test: random vibrations in three axes between 5 and a couple of,000 Hz By having an acceleration of 8.8 G.Sound test: 130 decibels at frequencies from 40 to 10,000 Hz for Half-hour.As the Speedmaster did pass each of the tests and the other candidates failed to (Longines and Rolex, down the line Bulova), the Speedmaster also didn't turn out unscratched. The luminous material for the hour markers was deteriorated along with the rate was impacted by the decompression and acceleration tests. Though, it passed every one of the tests and yes it was officially certified by NASA.Little Details Make DifferenceThe NASA tests were (nevertheless are) a true challenge for any watch and also the Speedmaster survived. It is one reason why I get a lot of respect just for this watch in particular. Understandably, Omega still managed to incorporate a complicated design. It would be the details inside the full Speedmaster range that make each reference so specific. The 105.003 isn't a exception. While the general looks serve the functions, the main points make the difference without disturbing the measurement, accuracy, etcetera. The 105.003 is the last series together with the straight lugs-case. At a later date, the Speedmaster will evolve much more using an asymmetrical case/crown protector. Again, it turned out Jim Ragan who suggested Omega to make an instance with better pusher/crown protection following a series of tests.Omega Speedmaster 105.003-64 "Ed White Tropical"Further readingOf course, we've featured this subject and watch already in past times.
