The Montblanc 1858 line draws inspiration from the Minerva professional watches of the 1920s and 1930s, designed for military use and exploration. Reinterpreting these historic models, Montblanc 1858 expresses the spirit of alpine excursions, embodying the modern trend of returning to nature. The Montblanc 1858 Geosphere Limited Edition 1858 is dedicated to the “Seven Summits” global mountaineering challenge, the “Holy Grail” of mountain excursions. The 42 mm bronze case features beige details contrasted with brown elements, which draw inspiration from the colors of the deserts. The timepiece is equipped with an in-house universal time complication, developed by Montblanc watchmakers in Villeret: two domed globes that rotate in opposite directions completing a complete evolution in 24 hours. Both are surrounded by a scale with the 24 time zones, together with a day/night indication with contrasting colors that allows you to better appreciate the various time zones, thanks to the luminescent continents, which guarantees greater visibility and better performance in the dark. The timepiece is completed with a Sfumato brown calfskin strap with beige stitching.
