General product information
The watchcase is made from a TITANIUM alloy bar with a diameter of 70 mm, undergoing numerous chip removing operations and various dimensional checks. Before the micro-peening finishing process, the watchcase is assembled and tested for pressure and water resistance in autoclave at 100 Atm (corresponding to a pressure of a water column more than 1000 meters high.The turnable bezel is provided with a reference index made of GOLD and is secured on the watch glass retaining ring by 3 special hexagon socket head cap screw located in the protuberances. These screws engage a groove on the ring and allow the bezel to rotate. A leaf spring pushes up the turnable bezel, forcing the screws to enter the cavities present on the watch glass retaining ring and preventing random rotation of the bezel. To choose the position of the reference index, it is necessary to push down the turnable bezel towards the watchcase and turn it either to the left or right, releasing it in the desired position. The admission resolution is equal to 2,5 minutes.
Bezel removal does not impair the watertight integrity of the watch.
The glass, made of organic polymer, is mechanically secured to the watchcase by 6 screws. Leak tightness is guaranteed by an O-ring seal with a large cross section. Tightness along the winding crown axis is obtained by means of an energized PFTE ring, which permits setting the watch even in deep immersions. The model identification number is engraved on the case back. The serial number is engraved on the body, in the inner part of the lower handle. A special screw is used for fixing the watchstrap. This screw is easily removable from each handle to allow replacing the watchstrap. This operation has to be done with the screwdriver included in the watch box.
