Abstract

The upper part of the case consists of sapphire glass (1) and covers the entire surface of the metallic lower part (2) of the case. The sapphire glass (1) is fastened to the lower part (2) of the case by means of screws (3), starting from the top. A sealing element (4), for example an O-ring, which is inserted between the upper and lower parts inside a joining line formed by the screws (3) guarantees that the case is closed in a watertight manner. <IMAGE>
