NASA has provided each of the Apollo astronauts with a standard issue Omega Speedmaster Professional manual-wind watch (pictured above) with Velcro strap. Unlike almost all other Apollo equipment, the watch was not manufactured specifically for use by NASA or in space but had been on sale in retail outlets in Houston and all of the United States from 1957-c1966 as the "Speedmaster" and as the "Speedmaster Professional "thereafter. Unlike most other devices Apollo, see was not produced specifically for use by NASA or in space, but was sold at retail stores in Houston and all of the United States from 1957 -- c1966 is "Speedmaster" and the Speedmaster "professional" then. Beginning in about 1962, NASA purchased a number of examples of commercially available watches for evaluation. Beginning around 1962, NASA purchased a number of examples of clocks available for commercial evaluation.
Aside from its primary and obvious function, the Omega Speedmaster Professional also incorporated a chronograph (stopwatch) via the large third hand on the watch dial. In addition to its primary and obvious, Omega Speedmaster Professional also incorporates a chronograph (stopwatch) through hands on third-largest dial view. The three interior dials on the face provided respectively a) a second-hand, ancillary to the conventional time function b) a minute elapsed counter for the chronograph and c) an hour elapsed counter, again related to the chronograph function. Three back on the interior provides an equivalent) Monday one hand, support the normal function of time b) a minute elapsed counter for the chronograph, and c) an hour elapsed counter, a more related to the chronograph function. The outside of the dial included a fixed bezel incremented to act as a Tachymeter (to measure miles per hour) in conjunction with the stopwatch function, hence the title "Speedmaster. Outside the back includes a fixed bezel incremented to act as a Tachymeter (to measure miles per hour) with stopwatch function, hence the title "Speedmaster.
The timepiece was intended to be worn for intra and extra vehicular activties including the moonwalks on all the missions. Timepiece was intended to be worn for more domestic and vehicular activties including moonwalks on all tasks. Environment inside a pressurised conventionally but the watch was worn during EVA (extra vehicular activity) the Astronauts wore the watch on the outside of their pressure suits, the long Velcro strap was designed to accommodate this change in 'wrist' dimension. Within a pressurised environment considered worn conventional, but the EVA (extra vehicular activity) of the astronauts even see outside in accordance with their pressure, long Velcro strap designed to accommodate this change the 'hands' size.
The Speedmaster had initially been worn on many of the pre-Apollo NASA Manned space missions after satisfactorily passing exhaustive tests aimed at determining performance reliability in the conditions likely to be experienced during EVA. The Speedmaster was the first step is to wear a lot of money on the NASA-Apollo manned space mission after the well comprehensive test to determine reliability performance in conditions likely to be experienced in EVA . The first American to walk in space Edward H. White wore a Speedmaster Gemini 4 during his spacewalk and there are some unconfirmed reports suggest that the manufacturer only discovered its use by NASA after that event. The first American space walk in Edward H. White wearing a Speedmaster his spacewalk during the Gemini 4 and there are some unconfirmed reports suggest that the manufacturer only detect its use by NASA after the event.
This model is still worn by many present day Astronauts on Shuttle missions. Model is still worn by many present day astronauts on space shuttle missions.

Of particular note, it is understood that see Buzz Aldrin has been lost in transit or during the period 1971 on the way to the Smithsonian Air and Space Museum while Buzz was trying to borrow items for display. Its current whereabouts are therefore not known. There's residence is not known. It may well be the first watch worn on the moon. It would be a first view worn on the moon. Buzz recounted in his autobiography that, during the EVA, Neil Armstrong left his Speedmaster own in the Lunar Module as a replacement for the in-cabin which timer had malfunctioned. Buzz has it in his autobiography that, in EVA, Neil Armstrong left his Speedmaster in particular Lunar Module as a replacement for the timer in-cabin which had malfunctioned.

2254.50 for me. I like the style better. My brother has the Bond version, and I prefer the baton style markers and sword hands of mine. You could add the 2254.50 to your collection and keep the bond.

I have the Bond, and will love to have the 2254.50... simply is a classic design just like the Bond, so why not having both

Political Correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

I went back and forth between the black dial and the blue dial for a few weeks until I finally settled on the blue. The black was very nice (and is in my future), but I ultimately settled on the blue because I feel that it's more versatile. Black watches to me are always dressier than they may actually be, and I don't get to dress up very often, so I went with the blue to go with my jeans/t-shirt kind of style.
Do you hate the orange bezel PO because it's not black too?

I'm not sure if this is the article you were thinking of, but it does discuss the topic: Who Makes a Better Movement - Rolex or Omega?
