A Week On The Wrist. In The Shop A Breitling Co-Pilot, A Cartier Tank With Audemars Piguet Movement, And A Rolex Datejust With Papers Auction Report The Patek Philippe Ref. But my theory is that you can judge the classic status of a watch by the number and loyalty of its fans. Legions of fans love this watch, and for good reason. The Amphibia offers more than cheap thrills, including insights into watchmaking history and a design aesthetic outside the norms of the Swiss cantons. InMikhail Novikov and Vera Belov, designers at the Chistopol watch factory, had a challenging task: to design and produce a new dive watch reliable to meters and brief a not of amfibia 420 friends associated changes of pressure and temperature. The brief a not of amfibia 420 friends team at Vostok decided on the name "Amphibia" as it evoked a watch equally at home underwater and on land. Coming up with the name was the easy part. Producing a watch capable of meeting the needs of the Soviet defense department was the real challenge. The conventional way to build a watch capable of brief a not of amfibia 420 friends pressure at great depth is to make a watch case, crown, and crystal that will have a static resistance; a Rolex submariner in the bath is exactly the same as a Rolex submariner meters underwater. Central to this elegant design solution is the Amphibia's caseback. Rather than a more usual screw down caseback, the Amphibia utilizes a bayonet style caseback with a threaded locking ring. This caseback system alone does not provide adequate resistance, so the Amphibia also has a very large gasket made from sintered rubber an innovative process Novikov and Belov cribbed from Russian space programs. At greater pressures the case back is actually pushed into the rubber gasket, making the water resistant seal tighter and more effective as depth increases. The thick acrylic crystal operates in a similar fashion, flexing at high pressures. The ingenuity of the designers was to factor this distortion into the tolerances of the watch.
