Although the Swiss Precious Metals Control Act of 1880 defined standards for gold and silver watch cases, the British Merchandise Marks Act of 1887 caused several changes in Swiss hallmarking, in particular the two Swiss standards for silver were not accepted in Britain, and the British also inadvertently caused the Swiss to create their own national brand or trade mark "Swiss made".

Swiss hallmarking before 1880 and after 1933 is rather outside the scope of this page, but I mention some of the changes made in 1933.

Eighteen carats is exactly 75% or 750‰ gold, from 18 / 24 = 0.75.But the British Merchandise Marks Act of 1887 forced a change.These hallmarks marks are seen on the vast majority of Swiss watches with silver or gold cases imported to the UK between 18 before assay and hallmarking of the cases of imported watches in a British assay office became compulsory. Items marked with the symbols introduced in December 1880 were obviously marked after that date.
