Sweat bleeds the cover slip generally not tight enough to keep sensitive metal parts of the Dial side au sohtttsseno

In one respect, the invention was therefore set as the task of permanently protecting the watch parts on the dial side against corrosion.

The dielectric and absorbent, especially metallic, cables of the covering can also be made up of mixtures of different substances in order to achieve certain indices of refraction In the case of atomization, various substances are transferred into the gas phase. In the case of the cathode sputtering process for the formation of dielectric layers by cathode sputtering, it has primarily proven successful that the elements are atomized in a residual gas atmosphere of the desired compound, in particular in a residual oxygen gas atmosphere, and then into the connections, i.e. preferably in The oxides are transferred by using several sputtering cathodes made of different elements * one obtains mixed layers of a desired two types of veins. ff-Inselne is covered with a decoction in the event of a coating process, or covered with substances to prevent condensation, one achieves a different structure _{or similar}
