Lange 31 'Platinum' is a deceptive-looking watch in its simplicity. But however simple it may appear with its modest silver dial, there are no other wristwatches in the market similar to it.
Its uniqueness is showcased in one full charge of the movement, which powers the timepiece for 31 days, as the name of the model suggests. The movement, powered by two large and powerful mainsprings stacked together and giving the watch enough kinetic energy for 31 days, is coupled with a complex remontoir escapement to avoid severe overbanking of the balance from the extreme power. This escapement is as difficult to adjust and regulate as a tourbillon escapement would be.
