Use of non-magnetic coating for covering components in a clock movement |
摘要 |
The present invention proposes to improve the yield of a micro-generator ( 1 ) used for operating a timepiece. This micro-generator operates on the basis of the phenomenon of electromagnetic induction; it is thus desirable to limit the presence of magnetic masses in proximity to said generator as much as possible. Research carried out has shown that the finish coating covering the movement-blank parts ( 11, 12 ) arranged in proximity to the micro-generator brakes the latter when it is made of a magnetic material, and in particular a ferromagnetic material. Thus, the exclusive selection of non-magnetic materials for manufacturing the movement-blank and its coating is proposed.
