The timepieces of the collection Montblanc 1858 are sports watches with a vintage taste inspired by the desire to reconnect with nature and the history of Montblanc. The design codes are reminiscent of military chronographs Minerva of the 20s and 30s, introducing in 2020 a new capsule collection on the theme of blue as a tribute to glaciers and snow-covered alpine landscapes.
The timepieces Montblanc. of the 1858 line carry on the tradition of over 160 years of history of Minerva manufacture exploring haute horlogerie in depth with collections that combine past and present through design, style and technical innovation. Precise, legible and able to withstand the most extreme conditions, the legendary professional watches Minerva of the 20s and 50s were made for military use and for exploration in the mountains. Montblanc. reinterprets these historic timepieces by presenting new models in shades of blue and ice, combined with a mix of materials such as titanium and ceramic that highlight three different levels of craftsmanship.
Montblanc. reinterprets a historic military monopusher chronograph Minerva by 44 mm 17/29 gauge 30s, with a very special dial featuring a spiral tachymeter scale in the center and a telemetry scale on the inner edge. The new Montblanc 1858 Split Second Chronograph Limited Edition 100 specimens features a vibrant blue look crafted in gradient enamel paired with a sturdy 44mm case in fully satin-finished grade 5 titanium. The dial is expertly crafted in solid gold and enriched with gradient blue grand feu enamel, which gives it an incredibly luminous appearance. Grand feu enamelling is one of the oldest and most precious techniques in the watchmaking sector, which gives intense and delicate shades of magical depth.
Like the original timepiece, the Montblanc 1858 Split Second Chronograph it has a beige telemetry scale that frames the dial. The rangefinder was very common in the legendary chronographs Minerva and adds functionality and a vintage touch to this new timepiece. Thanks to the rangefinder, it is possible to measure the distance of a visible and audible phenomenon, such as lightning and thunder during a thunderstorm. The chronograph hand is activated when the phenomenon is visible (lightning) and stops when the sound is heard (Tuono). The position on the scale shows at a glance the distance in kilometers that separates the phenomenon from the observer (or, in the case of the example, the observer from the storm). Calibration is based on the speed at which sound travels through the air, which is approximately 340 meters per second.
The timepiece also features a spiral-shaped tachymeter (with base 1000) in the center of the dial, which allows you to measure a maximum time interval of three minutes instead of one minute, as in the traditional chronograph scale located around the dial. The tachymeter scale indicates the speed of a moving object, such as a car, over a given distance. When the machine passes the starting point of the measured path, the length of which corresponds to that used for the basic calibration, the chronograph hand is activated, which is then stopped when the machine passes the arrival point. The number indicated by the hand on the tachymeter scale represents the speed in kilometers or miles per hour.
This function is combined with a complex rattrapante complication (Split Second), developed by the Maison's engineers, which allows you to measure intermediate times without interrupting the constant measurement of a longer time interval. The rattrapante function can be admired through the sapphire crystal case back, as in all timepieces equipped with this function. For better readability, the chronograph indications are shown via a beige central chronograph seconds hand with coordinated notches, while the split-seconds hand is orange, also with notches of the same color. The chronograph minutes counter is positioned at 3 o'clock.
Il Montblanc 1858 Split Second Chronograph Editione Limited to 100 pieces, it features the Manufacture caliber monopusher chronograph MB M16.31, characterized by two column wheels, a horizontal clutch system and a power reserve of 50 hours. The movement is an evolution of the caliber MB M16.29, which draws inspiration from the original caliber Minerva 17.29 developed in the 30s, used in both pocket and wrist watches. The caliber MB M16.31 is the direct heir of the 17.29, and, like its predecessor, is composed of the same iconic V-bridge (whose design was patented in 1912) and a large balance wheel with 18 screws that beats at the traditional frequency of 2,5 Hz / 18.000 A / h. Furthermore, the caliber MB M16.31 it further ennobles its predecessor thanks to a very high level of watchmaking mastery, characterized by hand-made finishes and masterful savoir-faire.
La Montblanc manufacture di Villeret is a special place that possesses the savoir-faire needed to produce an A-to-Z movement and capable of making all major components in-house, such as silver plates and bridges with
traditional hand-made decorations, as well as the entire regulating system, including the internal spiral. The caliber MB M16.31 it is particularly precious thanks to the traditional hand-made finishes, such as the pattern Cótes de Genève, the internal corners, the perlage and the bevel, techniques entirely made in Montblanc manufacture di Villeret. The rattrapante mechanism located in the center further enhances the entire movement. Completing the design is a handcrafted blue Gradient alligator strap Florence leather goods. The price of each single numbered copy is EURO 40.500.
