In reference to the new collection of timepieces featuring deep-blue galvanised dials, A. Lange & Söhne chose to collaborate with visual artist Sebastian Kite. At the Saatchi Gallery in London, he interpreted the power of the colour blue in an immersive site-specific artwork, entitled “Continuum”.

Winding these gigantic mainsprings would be exceedingly laborious if this A.Lange & Sohne Glashutte I/Sa Doppelfederhaus Replica were equipped with a normal winding crown, so A. Lange & Söhne revived the winding key in the epoch of pocketwatches, modernizing the twisting mechanism using an innovative ratchet and torque limiter.When Lange launched the Zeitwerk, it heralded the eye because its “new face.” At the time of this introduction, then-CEO Fabian Krone described the Zeitwerk since Lange’s most important brand new watch since the Lange 1. The watch achieved a very hard task: the motion managed to give enough energy to rotate the three relatively heavy disks used in its time display, two for the minutes and one for the hours, and then make sure that all three disks moved at precisely the same instant at the close of every hour. Achieving this required some intricate mechanisms, including a constant-force escapement with remontoir spring similar to that utilized in the Lange 31 (see Lange 31 thing). The watch also has a fly vane, shaped like a small revolving doorway, which offers air resistance and thus guarantees that the discs’ jumps aren’t too strong.
