The Montblanc Iced Sea Automatic Date 0 Oxygen with black glacier pattern dial gives the impression of looking into the depths of a glacier. Inspired by the Mer de Glace, this glacial texture was achieved using an almost-forgotten ancestral technique called gratté-boisé. The timepiece is housed in a 38 mm stainless steel case totally devoid of oxygen and comes with a unidirectional rotatable bezel with black ceramic insert, an embossed case back, and an interchangeable stainless steel bracelet with fine adjustment system. The timepiece conforms to the ISO 6425 norm for scuba diving and comes with a water resistance of 300 meters.
