The Montblanc 1858 Geosphere 0 Oxygen CARBO₂ Limited Edition blends innovation, sustainability, and exploration. Its 43.5mm titanium case is crafted using CARBO₂ — a pioneering composite made from captured CO₂ and recycled mineral waste. Entirely devoid of oxygen, the case prevents fogging and enhances precision. The black glacier-pattern dial features two rotating hemispheres for worldtime display, along with a 24-hour scale, day/night indication, and date. Powered by the MB 29.25 automatic manufacture movement, it’s finished with a 3D engraved titanium case back depicting Mont Blanc and a black textured rubber strap with fine adjustment system.
