What makes the Lange 31 is a unique watch in its realm is as there is no other wristwatches in the market similar to it. With one full charge of the movement, the Lange 31 can operate for 31 days as the name of the model would suggest and furthermore the technical complexion of constructing its movement is far beyond one can imagine. By stacking two large and powerful mainsprings it would permit the watch to have enough kinetic energy for 31 days. However, such extreme power for the drive train will eventually led to a severe overbanking of the balance. Simply said, to solve such a difficult situation, A. Lange & Söhne have chosen to incorporate a remontoir escapement as it’s solution. The complexity of developing this watch is as difficult to adjust and regulate as a tourbillon escapement would be.
