This makes it seem that only pilots could have bought watches downtown. This sounds very circumstantial. It is. We now have documentation evidence in the form NASA's original correspondence. Walter Schirra's colleagues repeatedly rejected requests for watches to be used as backup instruments.
Mercury was in serious trouble. NASA's top brass was not concerned about watches as they were too expensive and the rockets were still growing.
Donald Slayton, then-Assistant director for Flight Crew Operations,chopard fake watches was very interested in the situation when Schirra and Co. ended up in Earth orbit with untested gear. Unofficially, a number of watches, mostly chopard replica watchess but also Heuer, Bulova, and Breitling, had been lifted to the skies by that time.
To find evidence that NASA had begun to explore the supply of wristwatches to its crew,Rolex Replica Watches we must wait until September 1964. Slayton signed the document, stating that there was a need for a durable and accurate chronograph for Gemini and Apollo flight crews as an essential adjunct or backup to spacecraft timing devices .
Then, he listed a number of manufacturers that should be approached for an RFP. These were Elgin (sic), Benrus (sic), Hamilton, Mido (sic), Luchin Piccard (sic), Omega (sic), Bulova, Rolex (sic), Rolex (sic), Longine (sic), Gruen. The specification document by Slayton that follows is very technical. A peculiarity is the almost casual mixing of Imperial and metric units: "[The watch must be immune to variances in pressure in the range] from 50 feet ofwater positive pressure to anegative pressureof10-5 millimetresofmercury".

Point 6 is another indication that men at the top might not have been well-informed about the state of watchmaking. It states that "the chronograph may be manually or electrically operated ...". Of course, the first self-winding Chronograph didn't appear until at least five decades later. (although this author can confirm that there were a few fully-fledged Swiss selfwinding chronographs available as far back as the 1940s. But that's another story). Don't be fooled by the old saying that self-winding watches don't work in zero gravity. Thanks to the Conservation of Momentum, they work perfectly.
