Hublot Classic Fusion Chronograph Titanium 45 MM - Black Rubber Strap - Matte Black Dial - 521.NX.1171.RX

Titanium is widely used at Hublot, especially due to its lightness. It has the highest strength/weight ratio of all metals, making it a highly prized material in aeronautics. It also stands out for its resistance to corrosion and its inertness in contact with the skin. Hublot exclusively uses the highest quality titanium, grade 5, the hardest there is. After polishing, this material has a slightly bluish metallic sheen.
