In 2019, Montblanc introduced the impressive bronze variant of the 1858 family, the mono-pusher 1858 Split-Second Chronograph. Powering this timepiece is a movement that is anything but ordinary, made with 262 components and a balance that beats at 2.5 Hz, the hand-wound calibre M16.31 is a high-end movement that takes inspiration from the original 1930s Minerva calibre 17.29 pocket watch. Meticulously hand finished with tradition, the architectural depth and three-dimensionality is proudly displayed through the rear sapphire crystal.

Looking closer at the dial, one can depict heavy influences from historical Minerva military mono-pusher chronographs. Highly legible and practical, the glossy black dial is detailed with white snail-shaped tachymeter, cream colour telemeter scale and distinct red Arabic minutes indication. The cathedral-style hands with super-luminova is beautifully finished with a warm hue, perfectly capturing the essence of vintage aesthetics from the era.

Limited to 100 pieces and offered with its original full set accessories, this present example is certainly an extremely well-executed timepiece of true haute horlogerie.
