The Montblanc 1858 Monopusher Chronograph is one of the technical pillars of the Maison. In this new version, Montblanc reinterprets a historical Minerva chronograph with its calibre 13.20 from the 1930s. Like on the original timepiece, the 1858 Monopusher Chronograph features a black dial with a beige-colored railway track, as well as two counters at three and nine o’clock.
