The Montblanc 1858 collection is a tribute to the legendary professional watches produced by Minerva in the 1920s and 1930s for the army and exploration. Reinterpreting these historical models, the Montblanc 1858 Geosphere embodies the spirit of mountain exploration and fits into the current trend of a return to nature.
The design of the Montblanc 1858 Geosphere is a true nod to adventure. Its black dial, adorned with Arabic numerals and beige luminescent markers, contrasts with the 42 mm stainless steel case. The black and beige details add a touch of elegance and sophistication to this robust watch.
The Montblanc 1858 Geosphere is made with high-quality materials. The case is made of stainless steel, while the dial is protected by a domed sapphire crystal with a double anti-reflective treatment. The notched stainless steel crown is adorned with the Montblanc emblem in relief, adding a touch of luxury to this exploration watch.
With a diameter of 42 mm, the Montblanc 1858 Geosphere is perfectly balanced. Not too small to make the dial cluttered, nor too large to be cumbersome. It is water-resistant up to 10 bar (100 m), making it ideal for outdoor adventures.
