Montblanc 132300 1858 Automatic Men's Watch

The Montblanc 1858 Geosphere CARBO₂ 0 Oxygen Limited Edition 132300 is a timepiece that embodies innovation and adventure. Its 43.5 mm case is crafted from CARBO₂, a material produced through a pioneering process that captures CO₂ from biogas production and mineral wastes. The case is entirely devoid of oxygen, enhancing durability. The watch features a black dial with luminescent Arabic numerals and indexes, protected by a domed sapphire crystal with anti-reflective coating. Powered by the MB 29.25 automatic movement, it offers a world time complication with rotating Northern and Southern Hemisphere globes, a 24-hour scale, day/night indications, dual time display, and a date function. The titanium case back showcases a 3D colored laser engraving of the Mont Blanc mountain. Completing the design is a black interchangeable rubber strap with a pattern reminiscent of mountaineering textiles. Reference number: 132300.
