Ident No. 117838

Celebrating the 160th anniversary of Minerva, the Montblanc 1858 Geosphere honors the heroes of mountain climbing with a professional-grade, innovative timepiece. Built for those who travel the world in their perpetual quest for exploration, it expresses respect for true mountaineers as it is dedicated to the Seven Summits Challenge – the holy grail of climbers. The combination of materials such as steel and ceramic underlines the high quality and exclusiveness of this timepiece. On the dial, the world’s seven summits are marked with red dots on two turning globes and are also engraved on the case back. The timepiece features a new manufacture world-time complication developed by the Montblanc watchmakers in Villeret: two domed globes, turning in opposite directions, that complete a full rotation in 24 hours. Both are surrounded by a scale with the 24 time zones, along with a day and night indication in contrasting colors. This provides an instinctive way of appreciating the different time zones, aided by SuperLumiNova® applied to the continents for increased visibility and performance at night.
