The Squale 1521 Full Luminous Bracelet is the ultimate expression of technical innovation applied to professional diving watches. This exceptional timepiece reinterprets the legendary 42 mm “Von Büren” case in polished 316L stainless steel—a cornerstone of the brand since the 1960s—by blending it with a revolutionary concept of readability. The true star is, in fact, the “Full Luminous” dial: an entire surface coated in Super-LumiNova C3 that, in the dark or in the depths of the sea, glows completely with a vivid fluorescent light, offering perfect contrast with the black hour markers and hands.

Designed to withstand the most extreme conditions, it guarantees water resistance up to 50 ATM (500 meters). Structural security is ensured by the screw-down case back and crown; the latter is strategically positioned at the 4 o’clock position to prevent accidental impacts during dives. Inside, it is powered by the Swiss Sellita SW 200-1 automatic movement with Elaboré finishing, a guarantee of absolute precision and durability over time.

The watch’s technical and imposing look is complemented by a solid stainless steel link bracelet, which blends seamlessly with the polished lines of the case. Equipped with a flat, anti-reflective sapphire crystal and a unidirectional rotating bezel with 120 clicks for calculating decompression times, this model is an indispensable tool and a unique collector’s item.
