A. Lange & Söhne Zeitwerk Date Jumping Numerals in Action

Показать описание

In the ZEITWERK models, the constant-force escapement not only supplies the escapement with a steady flow of power, but it also generates the switching impulses needed to advance the jumping numerals. Like a puma preparing to pounce, the constant-force escapement must deliver a strong burst of energy. It is designed to execute a re-tensioning cycle precisely every 60 seconds. For a brief moment, the full torque of the mainspring barrel is released for re-tensioning. Instantaneously, this burst of power is used to switch the numeral discs.

Hope you enjoy the amazing German engineering through this short time-lapse video.
