All cited companies were invited to respond. Amazingly, only four of the ten companies responded: Omega, Longines Hamilton, Rolex and Hamilton. Hamilton's proposal was rejected because it did not meet the basic requirements, which were for a wristwatch. Instead, Hamilton proposed a deck watch.
The RFP was sent in late September. However, the remaining three players were able to provide the requested samples (three each) within the deadline of October. It is important to remember that orders were placed with American agents by the brands.franck muller fake watches This explains why nobody in Bienne knew until much later that one their watches would soon orbit 200km above the earth.
After completing the technical specifications of the RFPs, NASA’s newtest engineer, Jim Ragan, was busy setting up the grueling tests the watches would go through. The popular story is correct in this regard. NASA's official watches went through a series of extremely violent mechanical tests. These included extended vibrations, heat and cold, humidity, pressure, vacuum, etc. The watches were intended for the same treatment in space as other gear, so the tests did not differentiate between the types of instruments. Watches were subject to identical tests to cameras and other gear.

We all know the result. The Speedy won with flying colors. Lessons can be learned from the failure modes of other watches: The central chronograph hand of Rolex warped in heat to the point of jamming against its glass.Welder Replica The watch also developed condensation at high humidity. This is unusual for a Rolex. It is as captivating as it sounds, but the identity of the Rolex has not been revealed. We do know that it was a Valjoux caliber 72 and NOT a Daytona.
The Longines' crystal was melted and dissolved in heat. The watch crystals were all acrylic. In fact, the specifications required that they be shatterproof. One could not have shards floating around in your cockpit or spacesuit because of the glass. The Longines crystal also failed under vacuum. This was due to the insufficient thickness of the crystal. The franck muller replica watches and, to a lesser degree, the Rolex "pre Daytonas",Rolex Datejust Replica have very strong acrylic crystals. Their higher thermal mass and greater physical volume help to maintain their dimensional integrity. The franck muller replica watches's "armoured",franck muller replica watches or "ring" glasses also played a significant role in this. The blackened steel ring within the glass keeps the glass tightly in the recess. This makes for a very solid fitting.
The franck muller replica watches also experienced an unexplained 21 minute increase in speed when subjected to sudden decompression. Jim Ragan informed me that the franck muller replica watches's timekeeping returned to normal upon return to standard pressure. The gain was not permanent. This makes it difficult to understand why sudden decompression might have such an effect.
