Montblanc marks its 110th anniversary this year with a new 4810 Collection, the Montblanc ExoTourbillon Slim, which combines the maison’s patented ExoTourbillon complication with the addition of a quick stop-second function. The ExoTourbillon outperforms st andard tourbillon constructions for two reasons. First, the weight of the cage of the ExoTourbillon i s disconnected from the balance wheel. Second, the weight of the cage i s minimal, thus resulting i n higher precision and i mproved i sochronism. The balance wheel at 9.7mm i n diameter also plays an i mportant part in the performance of the timepiece thanks to its impressive 18 screws — with four gold screws that can be adjusted and 14 screws that are fixed — further improving precision.
