UPDATES, JULY 2024
Horopedia has updated the website with new videos containing definitions of horological terms basic explained by renowned Horologists (watchmakers), as well as a guided tour of the Vallée de Joux Technical School.
Committed to its educational mission, Horopedia has launched a series of short videos on basic horological terms, explained by key players in the industry – Horologists (watchmakers). The first four definitions available on the website cover the Main plate, the Barrel, the finishing Train (wheel train) and the Balance. These videos aim to highlight a component, a Complication, or a term as perceived by the master Horologist (watchmaker) himself.
In the Schools section, we have added a new video about the Technical School of the Vallée de Joux, which will celebrate its 125th anniversary in 2026 and is deeply embedded in the regional industrial fabric.
