The Montblanc 1858 product line is inspired by the professional Minerva watches from the 1920s and 1930s, which were conceived for military use and exploration. Reinterpreting these legendary timepieces, the Montblanc 1858 product line expresses the spirit of mountain exploration, embodying the modern trend of returning to nature. 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 colors of glaciers. The timepiece features a manufacture worldtime complication developed by the Montblanc watchmakers in Villeret: two domed globes turning in opposite directions, which 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 colors. 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 finished with a blue Sfumato calfskin leather strap with white stitching.

Care Instructions: If you have not worn your automatic or manually wound watch for a prolonged period of time, wind it fully by turning the crown twenty times. Further details are specified in the respective Service Guide.

In order to ensure the performance of your manually wound mechanical watch, we advise you to wind the crown once a day, preferably at the same time. Be careful not to force the crown once you feel resistance.

Do not change the hour or date between 10 p.m. and 2 a.m., the period during which the date changes, as this may result in damage to the movement. Please refer to the service guide for further details.

Do not expose your watch to temperatures higher than 60° Celsius (140° Fahrenheit) or lower than –10° Celsius (14° Fahrenheit). As your body and clothing will warm up the watch, its actual temperature will be different to the ambient temperature of your environment.

In case of a shock to the watch, consult a Montblanc boutique or certified Montblanc retailer. Even if no scratches or dents are visible, the movement may be damaged.

Do not wear other jewellery on the same wrist as your watch in order to preserve the patina of its surface and the integrity of the material. To preserve the pristine condition of your alligator, calfskin, satin or rubber strap, avoid contact with humidity, salty water, soap and cosmetic products. Do not treat your strap with wax, leather or shoe polish, as chemicals may damage the leather, lining or stitching. This may cause the strap to lose its original shine. Avoid prolonged exposure to high temperatures and direct sunlight to prevent the colour from fading. Please note that strong perspiration may darken the leather. Diamonds, set on a bezel or crown, must be handled with care to maintain the lifetime of their brilliance. Avoid contact with chemical products such as fragrances and detergents, as these substances will tarnish precious stones. If your watch has been exposed to such products, clean it with lukewarm water and a soft toothbrush. Then, rinse it with fresh water and use a soft cloth to dry it or let it dry naturally. Never expose it to a direct heat source. Additionally, please be sure to check the stones regularly to ensure they are still securely set.
