The Squale 1521 Classic Ref. 1521CL.VO is one of the last true icons of Swiss professional diving watches. Created around the legendary Charles Von Büren case introduced in the 1960s, it remains faithful to its original purpose: absolute reliability beneath the surface. More than half a century later, it is still built for those who appreciate authentic diving heritage rather than passing trends.

A Legend That Never Needed Reinvention

Before dive watches became luxury icons, Squale was already building instruments for professional divers.

The 1521 is not a modern tribute to a famous design.

It is the original.

Its legendary Charles Von Büren case is one of the very few dive watch designs to have remained in continuous production for more than fifty years. That longevity says everything about its timeless engineering.

The protected crown at 4 o’clock, the clean, highly legible dial and the signature orange minute hand were never created to impress. Every detail serves a practical purpose beneath the surface.

Powered by the proven Swiss Sellita SW200-1 automatic movement and water-resistant to 500 metres, the 1521 continues to embody the philosophy that has defined Squale since the beginning: build a genuine professional diving watch and let its reputation speak for itself.
