In addition to creating watches of its own, Squale – whose name derives from the Italian word for "shark" – was a major player in the production of dive watch
link cases. You might recognize vintage dive watches from the '60s,
link '70s, and '80s that
link featured the company's trademark case – with the signature four o'clock crown. Blancpain, Doxa, and TAG Heuer all called on Squale for its cases. Blancpain even used the Squale case on its famous "Bund" Fifty Fathoms for the German military!
