Squale Watch: Master Grand Grey MASTIBKG.TI20

Squale Master Grand Gris, a titanium diver with an anthracite dial

The Squale Master Grand Gris, reference MASTIBKG.TI20, features the Master collection's wave-patterned dial in anthracite grey. Light catches the contours of the dial, while applied hour markers and orange accents on the bezel enhance legibility.

The brushed Grade 5 titanium case measures 42 mm in diameter, 49 mm from lug to lug, and 15.5 mm thick. The screw-down crown is positioned at 4 o'clock. Domed, anti-reflective sapphire crystal protects the dial, whose hands and hour markers are coated with Super-LumiNova BGW9.

The Sellita SW200-1 Élaboré is a Swiss automatic movement with 26 jewels, beating at 28,800 vibrations per hour. It powers the three hands and the date display at 3 o'clock, with a power reserve of 38 hours.

The unidirectional black ceramic bezel features a brushed finish and highlights the first 15 minutes in orange. The Grand Gris offers a water resistance rating of 1,200 metres and a helium valve designed for saturation diving. Its brushed titanium bracelet complements the case's finish and fastens with a folding clasp.
