A tribute to the 160th anniversary of the Minerva Manufacture, the Montblanc 1858 Geosphere pays tribute to the heroes of mountaineering with an innovative professional timepiece. Made for those who travel the world always looking for new explorations, the timepiece expresses great respect for true mountaineers, since it is dedicated to the Seven Summits Challenge, the "Holy Grail" of climbers. The combination of materials such as bronze and ceramic highlights the high quality and exclusivity of this timepiece. On the dial, the seven peaks of the world are indicated by red dots on two revolving globes and are also engraved on the case back. The timepiece boasts a new compilation of the universal manufacture watch, developed by Montblanc watches from Villeret: two rounded globes that rotate in opposite directions completing a complete evolution in 24 hours. They are included in a scale with 24 hours, together with a day / night indication with contrasting colors, which offers appreciation at best in the various times, thanks also to SuperLumiNova® applied to the continents, which guarantees greater visibility and better performance in the dark.
