After having strived for the greatest heights, Montblanc explores the marine universe at 4810 meters below sea level with the Montblanc Iced Sea 0 Oxygen Deep 4810. The glacier pattern dial is inspired by the Mer de Glace - Sea of Ice - the main glacier of the Mont-Blanc Massif. Its texture was achieved using an almost-forgotten ancestral technique called gratté-boisé. Housed in a 43 mm titanium case totally devoid of oxygen with a shield protecting the screw-down crown, this diving watch comes with a case back adorned with a 3D engraving of the view divers see when diving underneath the ice. The timepiece is powered by Montblanc’s Manufacture, COSC-certified, automatic MB 29.29 movement, with approx. five days of power reserve and conforms to the ISO 6425 norm for scuba diving. It is water-resistant to 4810 meters.
