The Story

The Montblanc 1858 Monopusher Chronograph Limited Edition 100 pays tribute to the historical Minerva monopusher chronograph calibre 13.20, specially developed in 1920 for use in a wristwatch. This timepiece is the epitome of vintage chronograph design with its 40 mm stainless steel case. Reinforcing the vintage look, it features an original smoked-green dial and matching green alligator strap with beige stitching, coming from the Montblanc Pelletteria in Florence, Italy. Reminiscent of the iconic Minerva chronographs, it features a bi-compax dial with a small seconds counter at 9 o’clock and a chronograph 30-minute counter at 3 o’clock, as well as a tachymeter scale on the outer part of the dial. On the case back, the sapphire crystal reveals the beauty of the Montblanc Manufacture monopusher chronograph Calibre MB M13.21, composed of a large balance wheel with 18 screws beating at the traditional frequency of 18,000 A/H, a column wheel and horizontal coupling. This high-end, hand-finished movement features the iconic V-shaped chronograph bridge, whose design was protected in 1912, along with the iconic Minerva arrow decorated by hand.
