Gilding
Coating brass movement parts with a thin layer of gold, historically by fire-gilding (mercury amalgam).
Explanation
Gilding coats brass movement plates with a thin gold layer. Historically this was fire-gilding with mercury amalgam — effective but lethally toxic to the gilders — replaced by electroplating in the 19th century. Gilding protects against corrosion and gives the warm colour of English and Swiss movements; later 'gilt' finishes are often just lacquer or plating.
