Released in January of 2017 at the SIHH in Geneva, the Montblanc Heritage Chronométrie ExoTourbillon Rattrapante in a limited edition of 8 pieces is one of the most complicated and most expensive watches from Montblanc. Combining Montblanc's patented ExoTourbillon with a monopusher split-seconds chronograph, the beating heart inside this watch is of course a Minerva movement from Villeret. During the 1930s, the workshop’s fascination with recording elapsed time led to the production of split-seconds stopwatches, also known as “rattrapante” chronographs, from the French word “to catch up”.
