The Montblanc 1858 Iced Sea Automatic Date comes with a grey glacier pattern dial that gives the impression of looking into the depths of a glacier with all its minerals captured in time for millennia. Inspired by the Mer de Glace, this glacial texture was achieved using an almost-forgotten ancestral technique called gratté-boisé. The 41mm timepiece comes with a stainless steel interchangeable bracelet which can be quickly and easily switched for a black rubber strap with grey edging. It features a water resistance of 30m, Super-LumiNova® markings, and is adjustable on the wrist when wearing the watch for diving.
