The Montblanc 1858 Iced Sea Automatic Date Boutique Edition is fitted with a green glacier pattern dial, giving the impression of looking into the depths of a glacier thanks to an almost-forgotten ancestral dial technique called gratté-boisé. This boutique edition comes with both a stainless steel bracelet and a black rubber strap with green edging which can be quickly and easily switched thanks to Montblanc’s interchangeable system. Housed in a 41mm stainless steel case with a 3D engraving of a green scuba diver exploring an iceberg on the case back, it is also water resistance to 30m, includes Super-LumiNova® markings, and is adjustable on the wrist when wearing the watch for diving.
