The Squale 1521 is a classic diving watch in its most refined form. With a history spanning over 40 years, it is regarded as one of the most influential diving watches of the 1970s and it is still considered a blueprint for the ideal diving watch. 

Charles von Büren (the founder of Squale) designed this watch with the intention of creating an elegant yet robust watch that could meet the most demanding needs of professional divers. No frills, just pure functionality in every detail. 

This model is the latest Bund Special Edition with the Polished Case on the black rubber strap.
