Montblanc 1858 Monopusher Chronograph Watch

The Montblanc 1858 line is inspired by legendary professional watches produced by Minerva in the 1920s and 1930s for the army and exploration.
Reinterpreting these exceptional models, Montblanc 1858 reflects the spirit of mountain exploration and aligns with the current trend of returning to nature.

The Montblanc 1858 Monopusher Chronograph is housed in a fully satin-finished 42 mm stainless steel case adorned with a unique engraving on the back.
This model features a two-tone black and beige dial that recalls vintage watches and the colors of nature.

This timepiece, equipped with a tachymetric scale, is powered by Montblanc's MB automatic movement.
The Monopusher Chronograph watch is equipped with the caliber 25.12, which indicates measured times using a central seconds hand and a white 30-minute counter that contrasts with the black dial. The model is mounted on a vintage cognac calf leather strap.
