Apprenticeship
Apprenticeship with a length of 3 or 4 years are the most common ones. The certificate awarded after successfully completing a 3 or 4-year apprenticeship is called "Certificat Fédérale de Capacité" (), "Eidgenössisches Fähigkeitszeugnis" (EFZ) or "Attestato federale di capacità" (AFC).
Watchmaker
Historically, in England, watchmakers would have to undergo a seven-year apprenticeship and then join a guild, such as the "Worshipful Company of Clockmakers" in London, before selling their first watch. In modern times, watchmakers undergo training courses such as the ones offered by the BHI, or one of the many other schools around the world following the WOSTEP style curriculum. Some US watchmaking schools of horology will teach not only the wostep style, including the ETA range of movements, but also focus on the older watches that a modern watchmaker will encounter on a daily basis. In Denmark the apprenticeship lasts four years, with six terms at the Danish School of Watchmaking in Ringsted. The education covers both clocks and watches, as a watchmaker in Denmark is also a clockmaker. In France, there are three diplomas: the lowest is the (CAP) in horology (in two years), then the "Brevet des Métiers d'Art" horlogy for another two-year course. And optionally, the / DMA Horlogerie (two years).
