Gallet (ˈgæl.eɪ) is a historic Swiss manufacturer of high-end timepieces for professional, military, sports, racing, and aviation use.
Gallet is the world's oldest watch and clock making house with history dating back to Humbertus Gallet, a clock maker who became a citizen of Geneva in 1466.
The Gallet & Cie (Gallet & Company) name was officially registered by Julien Gallet (1806–1849) in 1826, who moved the family business from Geneva to La Chaux-de-Fonds, Switzerland.
Prior to this date, operations commenced under the name of each of the Gallet family patriarchs.
Gallet is best known during the 20th century to the present day for its line of MultiChron chronograph wristwatches. Produced primarily for military, industrial, auto racing, and other professional applications, Gallet's MultiChron watches often incorporated a number of advanced timekeeping innovations.
