1521 Blue Blasted Leather

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.
