Montblanc Iced Sea Automatic Date 41 mm Full Set 2023

A Dive Watch Signed by Montblanc

Unveiled at Watches & Wonders in 2022, the Montblanc 1858 Iced Sea Automatic Date marked a major milestone in the Maison's watchmaking history. Inspired by the spirit of exploration that has defined the 1858 collection since its inception, it became the first modern diving watch from the Manufacture to be certified according to the ISO 6425 standard, the international benchmark for professional dive watches. Far more than a simple stylistic exercise, the Iced Sea was conceived as a true tool watch, capable of performing in the most demanding environments while expressing a distinctive and sophisticated design identity.

To create this collection, Montblanc drew inspiration from the heart of the Alps, on the slopes of the Mont Blanc massif. Its name pays tribute to the Mer de Glace, France's largest glacier, whose dramatic landscapes, mineral tones, and fascinating depths served as the guiding inspiration for the entire project. This influence extends far beyond the name itself, appearing in every detail of the watch, from the extraordinary texture of its dial to the intricate engraving adorning its caseback.

The Watch

This reference MB129372 established all the design codes that define the success of the Iced Sea collection in an interpretation that is both elegant and highly versatile. Its 41 mm stainless steel case combines satin-brushed finishes with polished accents, achieving an ideal balance between strong wrist presence and everyday comfort. Carefully sculpted lugs and well-proportioned dimensions allow the watch to transition effortlessly from outdoor adventures to more refined occasions.

The black dial is undoubtedly the defining feature of the collection. Directly inspired by the frozen depths of the Mer de Glace, it is created using a traditional gratté-boisé technique, which reproduces the irregular texture of glacial ice. Multiple layers of lacquer are then applied to create exceptional depth and subtle reflections, allowing the dial to evolve beautifully as it catches the light from different angles.

To ensure outstanding legibility in every situation, the large applied indexes, the Arabic numerals at 12, 6, and 9 o'clock, and the cathedral-style hands are generously coated with Super-LumiNova®. The unidirectional black ceramic bezel also features a luminous marker at 12 o'clock, an essential characteristic of any true professional dive watch. Its precise action and exceptional scratch resistance further reinforce its practical credentials.

The caseback deserves special attention as well. Produced using advanced 3D laser engraving technology, it depicts a diver exploring beneath a towering iceberg. The interplay between polished and matte surfaces creates a remarkable sense of depth, once again reflecting the glacial landscapes that inspired the collection.

This version is fitted with a black rubber strap specially developed to provide exceptional comfort both during everyday wear and under more demanding sporting conditions.

Powering the watch is the automatic Montblanc MB 24.17 calibre, based on the highly respected Sellita SW200-1. It displays the hours, minutes, central seconds, and date at 3 o'clock. Renowned for its robustness and reliability, the movement operates at 28,800 vibrations per hour and delivers a power reserve of approximately 38 hours, making this Iced Sea an elegant and dependable companion for every adventure.
