1858 Geosphere 0 Oxygen South Pole Exploration Limited Edition Automatic 42mm Interchangeable Titanium, Ceramic and Canvas Watch, Ref. No. 7612582367544

Montblanc’s ‘1858 Geosphere 0 Oxygen’ watch has a storied past. It was worn by world-record holding mountaineer Nimsdai Purja while scaling Mount Everest, all without supplemental oxygen, hence its namesake. Continuing that legacy, this ‘South Pole Exploration’ edition has a titanium case and blue glacier dial, representing both the Northern and Southern hemispheres and is complete with world-time complications. One of only 1990 pieces, it’s uniquely devoid of oxygen to ensure its mechanical precision over time, however harsh the environment.<br><br><i>For warranty information, please refer to details & care</i>
