The Montblanc 1858 Geosphere is one of the key icons of the Montblanc 1858 line with its two domed turning hemisphere globes and in-house worldtime complication. Inspired by the explorations of legendary mountaineer Reinhold Messner, Montblanc unveils the new Montblanc 1858 Geosphere Limited Edition 1858 that pays tribute to his five-week solo trek across the Gobi desert in 2004. Reproducing the rocky terrain color scheme, the timepiece harmoniously combines a micro-blasted bronze case with a special engraving on the case back, a bi-directional shiny brown ceramic bezel, a smoked brown and beige lacquered dial, and a matching vintage-brown sfumato calf strap.

We are also proud to have our partner Vontobel provide us with in-depth industry knowledge, featured in their latest "Swiss watch industry outlook". You can find it here: https://bit.ly/3mw6WEN​​

Montblanc uses a very special technique to highlight the Gobi desert on the back of the watch giving it an authentic rendering in 3-dimensions, providing depth and realism as if it was a photograph. Made of titanium, the metal must first be structured, which means that the decoration will be engraved by laser, taking into consideration the relief of the drawing. Then the desired finish (matt and shiny) is also achieved by laser.

Finally comes the coloring phase. The colors are created with laser-generated oxidation. It is the level of oxidation that determines the final color obtained (and desired). Montblanc is one of the most advanced Swiss manufacturers to use this technology on such a large surface.

Special attention has been paid to the dial with smoked brown to beige. A lacquered finishing combined with warm rose gold-coated elements, such as hands and applied indexes, complete the overall design of this modern tool-style watch. For great readability, the day/night indicator, the cathedral-shaped hands, the indexes, the compass indications, and the hemisphere globes are all coated with beige-coloured Super-LumiNova that has been applied by hand.

The Montblanc 1858 Geosphere Limited Edition 1858 is powered by the Manufacture automatic Calibre MB 29.25. The timepiece has two domed turning hemisphere globes at six and 12 o’clock, which are surrounded by a fixed scale with the 24 time zones and include a rose gold-coated and brown day/night indicator (for both the Northern and Southern hemispheres). The longitude reference meridian for both hemispheres is highlighted with a black line coated with Super-LumiNova. Furthermore, a second time zone, used as a home time indication, is located at nine o’clock and a date aperture (linked to the local time) is located at three o’clock.
