Squale 1521 Series – Iconic Professional Diver

The Squale 1521 “50 Atmos” is a true icon in the world of professional dive watches. Introduced in the 1970s, it has earned its place as a dependable, high-performance tool watch while maintaining a timeless design.

Its 42 mm 316L stainless steel case delivers 500 m / 50 ATM water resistance, paired with a flat anti-reflective sapphire crystal and the trusted Swiss automatic Swiss Sellita SW200 movement — a combination that has made it a favorite among divers and watch enthusiasts alike.

The unmistakable Squale crown at 4 o’clock, iconic bevelled lugs, and the unidirectional dive bezel make the 1521 immediately recognizable on any wrist. For collectors, the 1521 is more than a dive watch, it’s a piece of history.

Bold styling, highly legible Super-LumiNova indices, and robust construction ensure it performs both underwater and in daily life. Each model has its own personality, from classic black or blue dials to PVD-coated variations, making it perfect for anyone looking for a professional dive watch with character.
