A unique edition of Montblanc 1858 Geosphere 0 Oxygen Carbo2 presenting for the very first time at Only Watch an exclusive brand new material, 0 oxygen in the case and an amazing experience together with Montblanc Mark Maker Nimsdai Purja.

This one-of-a-kind timepiece joins the Maison’s series of “Zero Oxygen” and will introduce a new collection based on this piece that will be revealed in April 2024. Like all of Montblanc’s 0 Oxygen pieces, this unique watch features several benefits for explorers who need their equipment to work in harsh environments.

Zero oxygen inside the case not only eliminates fogging, which can occur with drastic temperature changes at altitude, but also prevents oxidization. Without oxygen, all the components last longer and will provide unfaltering precision over time.
