When the LANGEMATIK PERPETUAL was launched in 2001, it was the first mechanical wristwatch that combined a perpetual calendar with a Lange outsize date. Its calendar takes the different durations of the months as well as all leap years into account. Assuming the watch runs without interruption, a manual correction is only needed in 2100.

In the LANGEMATIK PERPETUAL, the spirit of perpetuity is leveraged by its timeless styling: its dial is made of solid silver, the appliques of solid gold. Hands filled with a luminous compound assure good legibility – after sunset as well. The self-winding movement with the patented ZERO-RESET mechanism and a three-quarter rotor in 21-carat gold and 950 platinum is designed to work reliably for many generations to come.
