The Montblanc 1858 Geosphere 0 Oxygen The 8000 pays tribute to mountaineers who defy the highest peaks in the world under extreme conditions. Its 42 mm titanium case, completely devoid of oxygen, eliminates fogging and prevents oxidation, ensuring increased precision and durability of the movement.
The dark gray Sfumato dial with glacier pattern is enhanced with orange touches, evoking the first light of dawn on snow-capped peaks. The three-dimensional rotating globes of the northern and southern hemispheres, with luminescent continents, provide an intuitive reading of 24 time zones, complemented by day/night indications, a second time zone, and the date. The notched bidirectional black ceramic bezel, adorned with luminescent cardinal points, adds a touch of functional elegance.
The titanium case ensures lightness and robustness, while the interchangeable beveled titanium strap, equipped with a fine adjustment system, offers optimal comfort. The case back is adorned with a 3D laser engraving representing K2 mountain, symbolizing the spirit of exploration and adventure.
