Montblanc 1858 Geosphere CARBO₂ 0 Oxygen Limited Edition

With this limited-edition watch, whose design is as robust as the innovation that brings it to life, Montblanc pushes the boundaries of the concept of oxygen, the central element of any daring climb, even further. The material used for the watch case, CARBO₂, is made using a pioneering process that captures CO₂ from biogas production and mineral waste from recycling plants. To further underline the adventure theme, the 43.5 mm, completely oxygen-free case is enhanced on the side by a luminous blue outline engraved with Mont Blanc, while a colorful 3D laser engraving of Mont Blanc adorns the titanium case back. This timepiece is powered by the MB 29.25 automatic movement featuring the Montblanc manufacture world time complication, which includes rotating northern and southern hemisphere globes, a 24-hour scale, day/night indication, a second time zone, and a date. An interchangeable black beveled rubber strap, featuring a precise adjustment system and a pattern reminiscent of the textiles used by mountain enthusiasts, completes the model.
