moon watch 的STATEMENT OF SPECIFICATIONS :
1. Accuracy - Must not gain or lose more than 5 seconds over a 24 hour period. Desirable to have an accuracy equal to or better than 2 seconds per 24 hours.
2. Pressure Integrity - The chronometer [sic] must be immune to large variances in pressure to include a range from 50 feet of water positive pressure to a negative pressure of 10 millimeters of mercury.
3. Readability - All disks, bands, and figures must be readable in various lighting conditions. The chronograph must be readable under both "red" and "white" lighting conditions to or beyond a 5 foot candle illumination intensity. Either a black face with white figures and numerals or black on white is satisfactory. The chronograph should not cause glare at the high illumination levels. A stainless steel case with a satin finish is preferred.
4. The chronograph must have stop-start elapsed dials with
a. Seconds to 1 minute
b. Minutes to 30 minutes
c. Hours to 12 hours or greater.
5. The chronograph must be shockproof, waterproof, and antimagnetic. In addition, the face cover must be shatterproof.
6. The chronograph may be powered electrically, manually or the self-winding type; however, it must be capable of being manually wound and re-set.
7. Reliability - the Manufacturer must guarantee the watch to operate properly under normal conditions for at least one year time period. Performance data and specifications should be supplied by the manufacturer. Manufacturer guarantee and/or warranty should also be included.
NASA的測試條件 !
High temperature: 48 hours at 71º C followed by 30 minutes at 93º C. This under a pressure of 0,35atm and relative humidity not over 15%.
Low temperature: Four hours at -18º C.
Temperature-pressure: 0,000001atm and temperature raised to 71º C.
Temperature then lowered to -18º C in 45 minutes and again raised to 71º C in 45 minutes. This cycle was repeated fifteen times.
Relative humidity: 240 hours in relatuve humidity of at least 95% and at temperatures varying between 20º C and 71º C. The steam had a pH value of between 6,5 and 7,5.
Oxygen atmosphere: Exposure to 100% oxygen atmosphere at a pressure of 0,35atm and a temperature of 71º C for 48 hours.
Shock: Six 11 millisecond shocks of 40g each in six different directions.
Acceleration: Linear acceleration from 1g to 7,25g within 333 seconds.
Decompression: 90 minutes in a vaccum of 0,000001atm and a temperature of 71º C and 30 minutes in the same vaccum but at a temperature of 93ºC.
High pressure: Exposure to 1,6atm for one hour.
Vibration: Three cycles of 30 minutes (lateral, horizontal and vertical), the frequency varying from 5 to 2000cps and back to 5cps in 15 minutes. Average acceleration per impulse 8,8g.
Acoustic noise: 130db over a frequency range from 40 to 10000Hz for 30 minutes.

March 1, 1965 - NASA的測試結果 :
a) Rolex - It stopped running on two occasions during the Relative Humidity Test and subsequently failed during High Temperature Test No. 1 when the sweep second hand warped and was binding against the other hands on the dial. No further tests were run with the Rolex chronographs. b) Longines Wittnauer - The crystal warped and disengaged during the High Temperature Test. The same discrepancy occurred on a second Longines Wittnauer during Decompression Test No. 8. No further tests were run with Longines Wittnauer chronographs. c) Omega - It gained 21 minutes during the Decompression Test and lost 15 minutes during the Acceleration Test. The luminescence on the dial was destroyed during testing. At the conclusion of all testing the Omega chronograph operated satisfactorily. The results of operational evaluations by the astronauts show a unanimous preference for the Omega chronograph over the other two brands because of better accuracy, reliability, readability and ease of operation. 另外三隻經過認証,可供太空人選擇的space watch ! The Omega® X33 Chronograph is a more sophisticated watch, with analog and digital displays, and several timers that can be helpful during the course of experiments or other closely monitored activities. The Casio® G-Shock® is another basic watch, but it features a digital face and several timers—helpful when working on precise projects. The new watch for astronauts is the Timex® Ironman®. This cutting-edge timepiece, which sells for less than $100, boasts a light-emitting diode (LED) port to synchronize up to 10 alarms to the calendar of a personal computer, stores 38 telephone numbers, identifies messages, displays the time in two different time zones, and comes close to serving as a wrist computer. |
