1521
The famous Von Büren case back: Refinement in pursuit of reliability

The “1521” is the iconic collection par excellence of the Squale brand, and takes its name from the original production reference that Von Büren gave to this case back in the 1960s. To this day, it has remained faithful to the original. It was designed and built by Charles Von Büren at a time when diving watches were just beginning to appear, with its 50 atm of pressure resistance, guaranteeing peace of mind to all underwater exploration enthusiasts.

The crown at four o’clock
Functionality in every detail

The position of the crown at four o’clock has over the years become one of the trademarks of the Squale brand. Much more than just an aesthetic detail, it was designed in this way to avoid accidental knocks during a dive, which could cause it to become unscrewed, damaging the watch.

The bezel with 120-click adjustment
Maximum precision for diving safety

The unidirectional, anti-slip, knurled bezel with 120 clicks allows for precise measurement of dive time. By aligning the bezel reference with the minute hand at the moment of entering the water, the diver can keep track of elapsed time and manage the dive profile in relation to no-decompression limits and their dive plan. The bezel thus provides an immediate and reliable indication of the time spent underwater, while remaining pressure and air supply are monitored through the pressure gauge.
