The Montblanc 1858 Iced Sea Automatic Date is Montblanc's first sports diving watch, inspired by the Mer de Glace, the main glacier of Mont Blanc. The blue dial with a "glacier" pattern is made using an ancestral technique called graté-boisé, while the unidirectional ceramic bezel and engraved caseback make it ISO 6425 compliant.
