About Squale

Charles von Büren began assembling watches under his name as early as 1948. In 1959, von Büren registered the Squale trademark in Neuchâtel, Switzerland.

During the 1960s and 1970s, Squale provided cases for a multitude of brands, including but not limited to: Altanus Genève, Arlon, Potens Prima, Prima Flic, Jean Perret Geneva, Ocean Diver / Blandford, Deman Watch, Carlson Tavernier Geneva, and Sinn. Cases designed for 500m water resistance with the crown located at the 4 o’clock position were sold to Airin, Dodane, Blancpain, Tag Heuer, Doxa, Zeno, and Auricoste. Squale also supplied the Folgore Parachute Brigade, part of the Italian Air Force, and the Italian Navy’s Diving Corps with timepieces during this period.

Squale entered the watch market as an independent entity in 1974. However, in 1989 the company halted their production of mechanical watches in order to focus on quartz timepieces due to thequartz crisis.” As a result, theSquale Rambo was created. Unfortunately, like many watch companies at the time, Squale began to fade from the international watch market.

After the retirement of Charles von Büren, the Maggi families and the former Italian distributors of von Büren watches partnered with one another and relaunched the brand in 2010 with its headquarters in Milan and watchmaking being done in Chiasso, Switzerland.
