Montblanc Watch 1858 Iced Sea Automatic Date

Montblanc Watch 1858 Iced Sea Automatic Date MB130810. 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 gratte-boise. While most glaciers are white or blue in colour, some also come in a deep emerald green colour thanks to iron oxides captured in the ice.
