5.0 out of 5 stars Background on Speedmaster, September 9, 2011

This review is from: Omega Speedmaster Professional Apollo 11 Limited Edition Mens Moonwatch 311.30.42.30.01.002 (Watch)

For those of you who are unfamiliar with Speedmaster watches, they were the first watch to be approved for professional use in space. Buzz Aldren wore one on the first moon mission, and was quoted saying:

"It was optional to wear while we were walking on the surface of the moon ... few things are less necessary when walking around on the moon than knowing what time it is in Houston, Texas. Nonetheless, being a watch guy, I decided to strap the Speedmaster onto my right wrist around the outside of my bulky spacesuit."

Unfortunately his watch was 'lost' in shipping on its way to the Smithsonian. Rolex, Longines-Wittnauer, and Omega were the three contenders to be endorsed by NASA for professional use in space. The watches had to perform within 5 sec per day after being exerted to the following conditions:

High temperature: 48 hours at 71° C followed by 30 minutes at 93° C (200° F)
Low temperature: Four hours at -18° C (0° F)
Temperature cycling in near-vacuum: Fifteen cycles of heating to 71° C for 45 minutes, followed by cooling to -18° C for 45 minutes at 10-6 atm
Humidity: 250 hours at temperatures between 20° C and 71° C at relative humidity of 95%
Oxygen environment: 100% oxygen at 0.35 atm and 71° C for 48 hours
Shock: Six 11ms 40 G shocks from different directions
Linear acceleration: from 1 to 7.25G within 333 seconds
Low pressure: 90 minutes at 10^-6 atm at 71° C followed by 30 minutes at 93° C
High pressure: 1.6 atm for one hour
Vibration: three cycles of 30 minutes vibration varying from 5 to 2000hz with minimum 8.8G impulse
Acoustic noise: 30 minutes at 130db from 40 to 10,000hz

The evaluation concluded in March 1965 with the selection of the Omega Speedmaster, which survived the tests while remaining largely within 5 sec per day rate.
