Montblanc and its bezel as a center of operations

Montblanc’s Bezel: A Prominent Center of Operations

Montblanc’s watchmaking tradition dates back to 1858, when Charles-Yvan Robert founded a watchmaking workshop in Villeret, in the Saint-Imier Valley. In 1909, Minerva began developing chronographs and quickly became one of the leading specialists in the manufacture of watches and chronometers. In 1923, he introduced his first hand-wound monopusher chronograph for wristwatches.

A century later, Montblanc unveils a chronograph function that demonstrates that it continues in the footsteps of the Minerva legacy, as it modernizes a timepiece from the past with innovative design, style and technical expertise. In this way, the house performs a double celebration. On one hand, the 165th anniversary of the founding of the Minerva manufacture and on the other the centenary of his first wristwatch chronograph movementthe caliber 13.20.

This historic 1923 caliber was reinvented in 2003 with new materials and finishes to give it a contemporary feel, although the original design remained the same and only the reference to caliber 13.21 was changed to which, this year, a new chronograph function has been added. The new Montblanc 1858 The Unveiled Timekeeper Minerva it takes the fluted bezel of the 1858 Minerva Red Arrow monopusher chronograph and transforms it into a chronograph function.

Unidirectional rotating bezel

The function is implemented with the unidirectional rotating bezelal (clockwise) to avoid any handling problems. The first click activates the chronograph; with the second, it stops and, with the third, it restarts. The bezel features 30 jumps/steps per full turn, so you can time 10 separate events in one full turn. Montblanc is one of the few watch companies to have developed this system and has filed several patent applications.
