Squale Master Grand Bleu Automatic Blue Dial Leather Strap Men's Watch MASTIBLBL.RAL

The Squale Master Grand Bleu combines professional diving specifications with a dial inspired by the movement of the ocean. Crafted from Grade 5 titanium, the brushed case measures 42mm in diameter, 49mm from lug to lug and 15.5mm thick, while a helium escape valve reinforces its suitability for saturation diving. Beneath the domed sapphire crystal with an anti-reflective coating, the blue dial features a three-dimensional wave pattern that creates depth and texture across its surface. Applied hour markers and hands filled with Super-LumiNova BGW9 ensure excellent legibility, while the unidirectional bezel is fitted with a brushed ceramic insert whose markings are also luminescent for improved visibility underwater.

Swiss Automatic Movement

Powering the Master Grand Bleu is the Swiss-made Sellita SW200-1 automatic movement in Elaboré grade. Operating at 28,800 vibrations per hour and equipped with 26 jewels, the calibre delivers approximately 38 hours of power reserve while supporting both hacking and hand-winding functions. The movement is protected by a screw-down crown and screw-in caseback, contributing to the watch's substantial water resistance of 120 ATM. Combining proven Swiss engineering with robust construction, the SW200-1 complements the Master Grand Bleu's role as a serious diving instrument designed for demanding underwater environments.

Rubber Strap

The Master Grand Bleu is fitted with a black rubber strap featuring an alligator-embossed finish and contrasting grey stitching. Measuring 20mm wide and secured by a brushed titanium buckle, the strap balances durability with everyday comfort. Designed for extended wear, it complements the lightweight properties of the Grade 5 titanium case and maintains the practical nature of the watch.

Titanium Case Design

One of the standout features of the Master Grand Bleu is its layered dial construction. The dial is built around a three-dimensional wave pattern that evokes the movement of the sea, while the applied indices and Super-LumiNova BGW9 enhance visibility in low-light conditions. The Master collection also introduces a brushed ceramic bezel with luminous markings, ensuring the diving scale remains readable beneath the surface.

The Grade 5 titanium case further distinguishes the Master Grand Bleu from other diving models in the Squale range. Combined with its helium escape valve and substantial 120 ATM water resistance, the watch is engineered to withstand the pressures associated with professional and saturation diving. These technical features, paired with the ocean-inspired dial, give the Master Grand Bleu a distinctive identity within Squale’s modern dive-watch collection.
