Montblanc 1858 Geosphere Carbo 0 Oxygen Limited Edition

This limited edition timepiece showcasing a design as strong as the innovation within, Montblanc pushes the concept of oxygen – the central element in any intrepid ascent – even further than before. The watch case material, the CARBO₂, is created using a pioneering process development that captures CO₂ from biogas production and mineral wastes from recycling factories. The 43.5 mm case totally devoid of oxygen comes with an engraved luminous blue outline of the Mont Blanc Mountain. The timepiece is powered by the MB 29.25 automatic movement with Montblanc’s Manufacture worldtime complication, which includes rotating Northern and Southern Hemisphere globes, a 24-hour scale, Day & Night indications, dual time display, and a date.
