之前東森有出一只老師牌一模一樣，只差皇冠改成"勞斯萊斯"
後來喉總改去賣減肥藥就再沒看過了。不知有無圖片可看。。說到這，好久沒看到表中的勞師來師了。。。。害我現在都沒笑話可笑

Daytona is a watch which is hard to replace

It's same to Omega Speedmaster

Each has its own taste and style

I love both 非常高興

我覺得那隻紅面的speedmaster也很好看, 可是它跟紅面的Daytona價差更是天高地遠.
不過, 非戰之罪啦.......

Agree！！
我同時擁有116520及Broad Arrow，的確有不同的味道裝白ㄘ

不過兩者都是黑面，因我個人覺得黑面比較經典、沈穩

copy一份1962年NASA為了替太空人選擇用錶，在雙子星計劃時，比較測試Longines Wittnauer, Omega Speedmaster and Rolex Daytona的計時錶，只有Omega明顯勝出。有魔力的Daytona則早早出局，指針還絞在一起，沒法走了。

Daytona迷們先別火大，我也有Daytona, 只是提出這樣的歷史紀錄，大家參考，品牌與價格未必等同於"品質"罷了

以下原文轉載自NASA報告

Gemini Program

In 1962, NASA decided to equip the astronauts of its future Gemini programm with a highly accurate, legible, resistant and reliable wrist chronograph.

Donald K. Slayton, head of the flight Crew Operations , took action to select the chronographs :

For the purpose of comparison tests, NASA purchased chronographs different brands from Corrigan's, a large retailer in Houston, Texas the following watches where purchased : Elgin, Benrus, Hamilton, Mido, Piccard, Omega, Bulova, Rolex, Longine and Gruen. Of theses only 3 where selected for the comparative evaluation testing :

Longines, Omega and Rolex (Omega movement : Omega 321 , Rolex movement : Valjoux 72 , Longines : Longines 13 ZN)

1965 first qualification program :

Model tested : probably 105.012 no documents found for the moment to firmly state this , but for sure a Speedmaster equiped with Omega 321 caliber

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 10-6 atm 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

Results of the tests :

Omega Speedmaster : gained 21 minutes during decompression test and lost 15 minutes during the acceleration test , the luminescence of the dial was lost during the test

Rolex Daytona : stopped running on two occasions during the relative humidity test and during the high pressure test when the sweep second hand wraped and press against the other hands

Longine Wittnauer : Crystal warped and disengaged during the high pressure test , same fault occured during the decompression test

Final conclusion : the Omega chronograph performmed satisfactorily

In 1965, NASA chose the Omega Speedmaster Professional as the official chronograph for the space program.

With the first Gemini flight (GT3) with astronauts Grissom and Young, the Speedmaster Professional became part of the standard equipment issued to the astronauts. The watch was worn on the outside of the pressure suit with the use of a large black velcro band.

The Speedmaster was worn during the first walk in space by an American, Edward White, in 1965. Two speedmasters were worn by each Gemini astronaut one set on mission time , the other one on GMT or Huston time.

1967 : Apollo Program

Due to its performance, reliability and success with the Gemini programm the Speedmaster Professional was selected again as the official chronograph by NASA for project Apollo.

Each astronaut wore one chronograph for spaceflight as a standard issue. Most, however, wore two during spaceflight. some astronauts have used other watches as backup only one speedmaster was issued to the astonauts.
