Abstract

The invention relates to a watch casing having a casing body (1) whose base opening (4) can be sealed by a screw connection through a casing base (5). In order to construct the watch casing to be easy to assemble and have a low weight, the aim being to avoid malfunctions of the clockwork due to dirt, the materials of juxtaposed faces of the screw connection form a material pairing with a low friction coefficient. The faces of the one part of the screw connection can be provided for this purpose with a silver layer (16) in accordance with a method likewise according to the invention. <IMAGE>
