The Montblanc 1858 Iced Sea Automatic Date, Montblanc’s first sports diving watch, is characterized by the glacier motif on the dial, thanks to which we enter the depths of this mass of ice. This green dial with glacier motif is inspired by the Mer de Glace, the main glacier of the Mont Blanc massif. The texture has been achieved by means of a practically forgotten ancestral technique called gratté-boisé. This watch features a unidirectional two-tone ceramic bezel, an engraved case back and an interchangeable black rubber strap with a precise adjustment system. The watch meets the ISO 6425 standard for diving watches and is water resistant to 300 meters.
