GEOSPHERE CARBO OXIGEN

With this striking and innovative limited edition, Montblanc is investing even more than ever in the concept of oxygen, the key element in any ascent. The case material, CARBO₂, is created through an advanced development process that captures CO₂ from produced biogas and mineral waste from recycling plants. Further enhancing the adventurous theme, the 43.5 mm oxygen-free case features an engraving of the blue, luminous outline of Mont Blanc on the side and a 3D laser-engraved outline of the mountain in color on the titanium case back. The watch is equipped with the MB 29.25 self-winding movement with the Montblanc Manufacture World Time complication, featuring rotating globes with the northern and southern hemispheres, a 24-hour scale, day and night indications, a Dual Time function, and a date. The timepiece is completed by an interchangeable, beveled black rubber strap with a precise adjustment system and a motif reminiscent of the fabrics worn by mountaineers.
