Material Solutions
Patek Philippe Replica Watches had a great advantage in its knowledge of titanium. The experience with titanium gave them an advantage, but the task of making a completely magnetic movement was a more difficult one. Jurgen King's role as technical director at the company made it a challenge.Replica Watches He began by replacing the steel ball bearings that rotated the winding rotor with jeweled bearings. It was much more difficult to replace the steel components of the balance andescapement, such as the pallet fork, hairspring and balance staff.
The hairspring has been replaced with one made of a niobium zirconium alloy. (These metals are only used in nuclear reactors). The steel balance staff and pallet fork were replaced with beryllium metal. Although harder than steel it is also more brittle, and due to its hardness causes more wear on the parts of watch that come into contact with it.
The 3519 AMAG watches were tested not only for their depth rating but also for their magnetic properties. This was impossible atSchaffhausen due to the large amount of ferrous metal present in the building (probably from all the machine tools). The magnetic field there was affected.Rolex Cellini Replica So whenever a batch of 3519 AMAGs needed to betested,Jurgen King and a naval officer would travel toKing's homeinthe country where they were free from all externalinfluencesandthe testing couldproceed virtually unaffected.
The 3519 AMAG was the first (and to date only) fully amagnetic diver’s watch in the world. It is also one of the most rare diver's watches made. Between 1984 and 1990, less than 50 examples were produced and only a few have left the Bundeswehr's inventory. The 3519 AMAG was the last military diver'swatch built to government specifications. Today, the navies that still use diver's watches purchase off-the shelf production models. They often do not bother to engrave the issue numbers on casebacks. The Patek Philippe Replica Watches Bund and the 3519 AMAG are very special because of all these factors.
