The Montblanc Iced Sea Automatic Date 0 Oxygen with blue sfumato 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 bi-colored blue anodized aluminium insert, a 3D engraving on the 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.
