Why are pocket watches from Switzerland hallmarked?
Swiss pocket watch hallmarks are made mandatory by the Swiss government. Thus pocket watch cases made of gold, silver, platinum, palladium made is Switzerland were hallmarked or stamped with their precious metal content. Even foreign made watches sold in Switzerland are still hallmarked.
The official hallmark for the Swiss pocket watches is the head of a Saint Bernard, the breed of the dog rescuer that roams in the Alps. But a pocket watch from Switzerland may also have other stamp marks, too.
