Montblanc 1858 Monopusher Chronograph

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 legendary timepieces, the Montblanc 1858 product line expresses the spirit of mountain exploration, embodying the modern trend of returning to nature. The Montblanc 1858 Monopusher Chronograph comes in a 42 mm full satin-finished stainless steel case with a special engraving on the case back. It features a black and beige two-tone dial that is reminiscent of vintage timepieces and depicts the colours of nature. The chronograph features a telemeter scale and is powered by Montblanc’s automatic MB. 25.12 Monopusher Chronograph Calibre that indicates elapsed time with a central seconds hand and a 30-minute counter, both with white hands to create a contrast with the black dial. The timepiece is completed with a vintage technical bracelet made of stainless steel.
