After the success of the Heritage Chronométrie collection at the last SIHH Montblanc adds two new models. One is this annual calendar based on one of the first Minerva chronographs from the 1920s. For the laymen among you: the renowned Minerva manufacture in Villeret has been in Montblanc hands for many years. It is the first time in this line that Montblanc combines an annual calendar with a chronograph.
