The Montblanc 1858 Iced Sea Automatic Date Boutique Edition, featuring a gray dial with glacier motif, conveys the feeling of gazing into the depths of a glacier with all its minerals frozen for thousands of years. Inspired by the Mer de Glace, this glacial texture has been achieved using a virtually forgotten ancestral technique called gratté-boisé. The 41 mm watch includes an interchangeable steel bracelet that can be quickly and easily exchanged for a black rubber strap with a gray outline without a trip to the boutique or the use of any tools. It can also be adjusted at the wrist when used for diving. The watch meets the ISO 6425 standard for diving watches and is water resistant to 300 meters and features luminescent markings for easy reading in low light.
