manufacture d'horlogerie

(meaning "watchmaking manufacturer") is a French horological term of art that is also used in English. In horology, the term is usually encountered in its abbreviated form manufacture. This term of art is used when describing either a wrist watch movement/watchworks fabricator or its products. The term is specifically reserved for those fabricators which make all or most of the parts required for their products in their own production facilities as opposed to assembling watches using parts purchased from other firms.
