Squale 1521 Watches

The Squale 1521 is the brand’s iconic dive-watch collection, tracing its origins to the case reference developed by Charles Von Büren in the 1960s. The collection takes its name from that original 1521 case and remains closely connected to Squale’s long-standing expertise in professional diving watches.

Built for serious underwater use, the 1521 features 50 ATM (500-metre) water resistance, a screw-down crown positioned at 4 o’clock and a unidirectional 120-click bezel. The offset crown is designed to reduce the risk of accidental knocks while diving, while the distinctive orange minute hand provides strong visibility in low-light underwater conditions.
