Relax. It’s just a Chinese knock-off.
If it were really Swiss, it would say “Peking Watch Company” on it. The Swiss got their start and were notorious for making knock-off watches. One Swiss fake in the 19th c were timepieces of a manufacturer in my state: “The New Haven Watch Co”. The Swiss were in part responsible for the 1890 law requiring imports to be marked with the country of origin.
