The Swiss government strictly enforces a law on “the protection of brand names and place of origin”, especially with respect to watches. For this reason, any watch bearing the words “Swiss Made” must adhere to this law, passed on August 28, 1992.
The rule was tightened in 2013 to require 60% “Swiss value” and again in 2017 to require 60 percent of value of a watch movement to be of Swiss origin. The calculation of this value can include production and assembly costs, research and development costs, and costs for quality assurance and certification. It does not include the cost of raw materials not available in Switzerland, packaging, transport, and distribution costs.
The law applies to any watch carrying on the outside the words “Swiss made” or “Swiss”, or any other use of the word “Swiss” in any language. According to Section 1a OSM, a watch is considered to be Swiss if
A Swiss movement is defined as follows in Section 2 OSM
If the movement is Swiss and the case is not, a watch may only contain the words “Swiss movement”. According to Section 3 § 3 OSM, the word “movement” must appear in full and be written in the same type-face, of identical size and colour, as the word “Swiss”.
