Montblanc Men Replica presents the most complicated timepiece yet in the Montblanc Villeret 1858 line-up, the ExoTourbillon Rattrapante. Montblanc’s Collection Villeret 1858 is its showcase for high end/high complication pieces.
This wrist High Quality Swiss Fake Watch combines a split-second chronograph and Montblanc’s patented four-minute ExoTourbillon. The ExoTourbillon gets its name from its unique design: its pocket-replica watch sized balance wheel, in-house balance spring, lever and escape wheel oscillate outside the presence of the tourbillon carriage; on top is a graceful and “infinitely” curvacious bridge.
Montblanc notes that such a construction is energy-saving in nature — energy which in this case can be used by the chronograph. Slowing the speed of the rotations (4 mins vs. 1 min traditionally) requires less energy from the barrel, but produces the same compensating effect as a speedier tourbillon. The hairspring with an upward Phillips curvature at its outer end oscillates at the traditional pace of 18,000 semi-oscillations per hour (2.5 hertz) and thus enables this chronograph to measure elapsed intervals to the nearest fifth of a second. The rotating cage is smaller and has less mass, so its rotary motion requires less energy as well.
Furthermore, the balance is freed from the weight of the rotating cage, which yields a further reduction in its energy requirements. Montblanc’s innovative device requires more than 30% less energy than conventional constructions, and this is advantageous for the functioning of the split-second chronograph. Another essential benefit ensues from separating the balance and the rotating cage: the accuracy of the balance’s amplitude is improved because the balance is not influenced by the inertia of the cage.
