Montblanc Iced Sea 0 Oxygen Deep 4810

Montblanc's Iced Sea 0 Oxygen Deep 4810 explores the marine world 4,810 metres below sea level, a figure that echoes the height of Mont Blanc. The glacier pattern dial, inspired by the Mer de Glace, owes its texture to gratté-boisé, an almost-forgotten ancestral technique. Its 43 mm titanium case, totally devoid of oxygen to prevent fogging and oxidation, features a shield protecting the screw-down crown and a case back with a 3D engraving of the view divers see beneath the ice. The COSC-certified automatic Manufacture calibre MB 29.29 offers approximately five days of power reserve, and the watch conforms to ISO 6425, with water resistance to 4,810 metres.
