The Montblanc 1858 Geosphere is dedicated to the world’s Seven Summit mountaineering challenge, the holy grail of mountaineering adventures. It comes in a 42 mm titanium case combined with blue and contrasting icy white design details, finding inspiration in the colours of glaciers. The timepiece features a 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 colours. 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. The timepiece is completed with a blue Sfumato calf leather strap with white stitching.
