Montblanc Heritage Chronométrie ExoTourbillon Rattrapante Limited Edition 8 square

 

 

Montblanc has let nothing stand in its way to achieve

this first-ever association of its patented ExoTourbillon, debuted in 2010, and

a monopusher split-seconds chronograph. Intermediate times are recorded by

stopping the split-seconds hand while the chrono seconds hand continues to keep

track of the ongoing measurement. Revered as one of the most complex to

produce, this complication is widely appreciated for its practical

applications. Here, it combines with the ExoTourbillon, thus named because the

screwed balance is positioned outside the tourbillon cage. Isolating the

balance this way allows for a smaller cage with less mass, thereby using 30%

less energy than a conventional tourbillon. Precision is more than ever at the

heart of this watch whose aesthetic is rooted in traditional fine watchmaking

and specifically the Pythagore watch, crafted by Minerva in 1948.
