The Montblanc 1858 product line is inspired by the legendary professional Minerva watches from the 1920s and 1930s which were conceived for military use and exploration. Reinterpreting these historical timepieces, the Montblanc 1858 product line expresses the spirit of mountain exploration, embodying the modern trend of returning to nature. The Montblanc 1858 Automatic 24H is highly-functional and dedicated to the modern-day explorer. It indicates the time on a 24-hour scale using a single luminescent red-coloured hand which not only indicates the time, but also acts as a compass. The timepiece comes in a 42 mm stainless steel case with a bronze bezel and a black dial with beige luminescent numerals and indexes. As a secret detail, the dial features a hidden luminescent map of the Northern Hemisphere that is only revealed at night. The Montblanc 1858 Automatic 24H is completed with a refined black textile strap that is made in a traditional 150-year-old strap manufacture in France.
