Montblanc, a name synonymous with luxury writing instruments and leather goods, has increasingly focused on horology since 1997. In , the brand surprised many by introducing the 1858 Iced Sea Automatic Date, its first dedicated dive watch collection. Now, Montblanc is refining that offering with a more compact release: the 38mm Iced Sea Automatic Date 0 Oxygen. This smaller iteration builds on the success of the original 41mm model, incorporating the brand’s innovative Zero Oxygen technology.
The 38mm Iced Sea maintains the core functionality of a dive watch, boasting water resistance to . The stainless steel case, measuring 12.3mm thick, features a unidirectional rotating bezel, essential for tracking elapsed dive times. Dial options include frosty white and arctic light blue, each paired with a corresponding ceramic or aluminum bezel insert. A blue-emission pip at the 12 o’clock position on the bezel enhances visibility underwater. The case finishing combines brushed surfaces with polished bevels, providing a sporty yet refined aesthetic.
However, the defining characteristic of this new model is the Zero Oxygen technology, initially introduced in the Iced Sea 0 Oxygen Deep 4810m. Inspired by mountaineering pioneers like Reinhold Messner, who famously conquered peaks without supplemental oxygen, this technology aims to improve the longevity and reliability of the watch movement. The case is sealed within a nitrogen-filled, oxygen-free environment. This process mitigates several potential issues: it prevents fogging caused by rapid temperature changes, reduces condensation, and, crucially, slows down oxidation within the movement. Oxidation is a primary cause of degradation in mechanical watches, so minimizing it can significantly extend service intervals and maintain accuracy over time.
The dial of the Iced Sea Automatic Date 0 Oxygen is designed to evoke the glacial landscapes of Mont Blanc, specifically the Mer de Glace. Montblanc achieves this textured effect using a technique called gratté boisé, where a wood tool is scraped across the dial surface to create a random, crystalline pattern. The blue dial variant further enhances this connection with a “sfumato” (smoked) effect, mimicking the color of icy mountain waters. Super-LumiNova is applied to the indices, numerals, and hands to ensure legibility in low-light conditions. A practical date window is positioned at 3 o’clock.
The watch is available with either a stainless steel bracelet or a rubber strap, both featuring glacier-patterned interiors and fine-adjustment systems for a comfortable and secure fit. The bracelet, in particular, is noted for its well-executed finishing and smooth articulation.
Beneath the surface, the Iced Sea Automatic Date 0 Oxygen is powered by the MB 24.17 movement. This movement is based on the Sellita SW 200-1 automatic caliber, a widely used alternative to the ETA 2824. While a reliable workhorse, the MB 24.17 offers a modest power reserve. This is a point of consideration given the watch’s robust capabilities and price point.
The Montblanc Iced Sea Automatic Date 0 Oxygen 38mm presents a compelling package for those seeking a capable and stylish dive watch. The attractive dial, coupled with the innovative Zero Oxygen technology, sets it apart from many competitors. However, the Sellita-based movement and its limited power reserve may give some potential buyers pause, especially considering the price. The watch retails for EUR 4,000 on a rubber strap and EUR 4,200 on a steel bracelet.
