Dive into the essence of the sea with the new Squale Master collection. The Grand Bleu and Grand Vert dials, inspired by the fascinating phases of freediving, capture the descent into the deepest blues and the ascent towards the green light of the surface. Each dial is a three-dimensional masterpiece, featuring a wavy structure that evokes the hypnotic movement of the ocean.

Unrivaled Performance, Flawless Visibility
Designed for the most extreme adventures, every detail is crafted to guarantee maximum reliability. SuperLuminova ensures impeccable readability even in the darkest abysses. With a water resistance of 120 ATM, a Grade 5 titanium case, and a 4mm thick sapphire crystal, the Master collection is ready to challenge every limit. The helium escape valve underscores its professional vocation.

A Reliable Heart, a Prestigious Legacy
Inside, beats the Sellita SW200 automatic movement, synonymous with precision and reliability. The new Master collection isn't just a watch; it's the evolution of a story Squale began in the 1960s, uniting tradition and innovation.
