It was only in October 2008 that Montblanc presented the Grand Tourbillon Heures Mystérieuses to celebrate the 150-year history of Minerva. Now, ahead of next January's Salon International de la Haute Horlogerie, the Montblanc Collection Villeret 1858 has been extended to include another new model. The Grand Chronographe Régulateur is further proof of the innovative impetus at the Institut Minerva de Recherche en Haute Horlogerie provided through cooperation with Montblanc, the aim of which was to generate one new movement every year.
