Montblanc 1858 Geosphere Carbo₂ 0 Oxygen Limited Edition - 1969 Parts

With this limited edition watch whose design is as robust as the innovation that gives it life, Montblanc further pushes the limits of the concept of oxygen, the central element of any daring ascent. The material used for the watch box, Carbo₂, is manufactured thanks to a pioneering process that captures CO₂ in biogas production and mineral waste from recycling factories. To further emphasize the theme of the adventure, the 43.5 mm case entirely devoid of oxygen is enhanced, on the side, of a engraved bright blue outline representing the white Mont, while a 3D laser engraving colorful Mont Blanc adorns the titanium housing bottom. This timepiece is animated by the MB 29.25 automatic movement with the universal hours of the Montblanc manufacturers, which includes the globes of the northern and southern rotary hemispheres, a 24-hour scale, the day/night indication, a second time zone, and a date. An interchangeable black interchangeable rubber bracelet, with a precise adjustment system and a pattern recalling the textiles used by mountain enthusiasts, completes the model.
