Capturing the Spirit of Mountain Exploration

1858 Geosphere

Dedicated to the world’s Seven Summit mountaineering challenge,
the holy grail of mountaineering adventures where climbers set out to ascend the highest mountains from each continent

The Watch Quote™ - January 23rd, 2018



Paying tribute to the 160th anniversary of Minerva, the Montblanc 1858 Geosphere embodies the spirit of mountain exploration with a professional and innovative timepiece that is destined for those who travel the world in their quest for exploration. This timepiece features a brand-new manufacture worldtime complication powered by the calibre MB 29.25, developed by the Montblanc engineers in Villeret.



The Montblanc 1858 Geosphere is dedicated to the world’s Seven Summit mountaineering challenge, the holy grail of mountaineering adventures where climbers set out to ascend the highest mountains from each continent. The Seven Summits challenge is recognized as the most difficult mountaineering quest worldwide and only 500 athletes have achieved the mission to date.



This timepiece features a worldtime complication with two turning domed hemisphere globes, which make a full rotation in 24 hours. The northern hemisphere at 12 o’clock turns anti-clockwise, while the southern hemisphere turns clockwise. They are both surrounded by a scale with the 24 time zones, along with a day/night indication in contrasting colours.



The longitude reference meridian for both hemispheres is highlighted with a white line coated with SuperLumiNova®. Additionally, a second time zone display is located at nine o'clock and a date (linked to the local time) is indicated in an aperture at three o'clock. With this new worldtime display of the two hemispheres, the Montblanc 1858 Geosphere brings a new instinctive way of appreciating different time zones.



The world’s Seven summits are marked on the globes with red dots, enhancing the spirit of mountain exploration. They are also engraved on the case back along with the unique drawing of the Mont Blanc mountain, a compass and two crossed ice pick-axes. SuperLumiNova® has also been applied to the continents for increased visibility and performance at night.



The black dial of the Montblanc 1858 Geosphere features contrasting colours with the addition of rhodium-coated or red gold-coated elements, depending on the models. The watch includes all the design codes from the 1858 collection with beige luminescent Arabic numerals and indexes, the authentic Montblanc logo from the 1930s, domed and resized cathedral-shaped hands, as well as a railway track that all come together in this highly legible, vintage-inspired timepiece.



The timepiece comes in two versions, with a stainless steel case or a limited edition bronze case. Both feature polished and satin-finishing as well as vintage fluted crowns with the Montblanc emblem in relief. A new bidirectional stainless steel or bronze bezel with shiny black ceramic completes the design. The bezel is also fluted on the flank for a better grip and features the four cardinal points which have been engraved.



The Montblanc 1858 Geosphere is water resistant to 100 metres and is certified by the Montblanc Laboratory Test 500. It comes on a choice of a high-quality black “NATO” strap, a cognac-coloured aged calfskin strap with beige stitching or a new brown Sfumato aged calf leather Bund strap with beige stitching, reminiscent of historical Minerva timepieces from the 1920s and 1930s that were equipped with this kind of strap and that were ideal for military use and mountain exploration. The Bronze series is limited to 1858 pieces, paying tribute to the year of foundation of the Minerva Manufacture.
