Editor's Notes

Montblanc's '1858 Geosphere' collection is inspired by "the holy grail of mountaineering adventures," the Seven Summits, which challenges explorers with climbing the highest peak on each continent. Built in Switzerland with a durable titanium and ceramic case and leather strap, this automatic reference is engineered with an innovative in-house complication: two domed, SuperLumiNova®-coated hemispheres representing the 24-hour day/night cycles of Northern (turning clockwise) and Southern (anticlockwise) respectively.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing
