The Montblanc 1858 Iced Sea Automatic Date Boutique Edition with its green glacier pattern dial gives the impression of looking into the depths of a glacier thanks to an almost-forgotten ancestral dial technique called gratté-boisé. While most glaciers are white or blue in color, some also come in a deep emerald green color thanks to iron oxides captured in the ice. This Boutique Edition comes with both a stainless steel interchangeable and adjustable bracelet and a black rubber strap with a new green outline which can be quickly and easily switched without the need to return to the boutique or the use of any tools. The 41mm timepiece is water resistant to 300 meters and features luminescent markings for reading in low light. This Boutique Edition also features a 3D engraving on the case back of a green diver exploring an iceberg.
