Complexity with 729 parts

The DATOGRAPH PERPETUAL TOURBILLON unites three significant complications: a flyback chronograph with a precisely jumping minute counter, a perpetual calendar with a moon-phase display and a tourbillon with a patented stop-seconds mechanism. The classically designed dial pairs elegance with technical functionality. All the displays of the perpetual calendar switch instantaneously and thus provide unambiguous readings at all times.

Movement L952.2

The assembly of the manufacture calibre L952.2 challenges the skills of the watchmakers. It takes considerable experience, dexterity and patience to guarantee the flawless interaction of the complex mechanical components. For the first time in a Lange tourbillon, the balance is calibrated to 18,000 semi-oscillations per hour. This corresponds to five semi-oscillations per second and thus to a frequency of 2.5 hertz. Accordingly, stopped times are displayed with an accuracy of one-fifth of a second.
