In 2009, A. Lange & Söhne debuted its original Zeitwerk design, at the time a revolutionary venture with its unique dial layout and combination of mechanical and digital components. Now, over a decade later, the esteemed watchmaker introduces the second generation of the Zeitwerk, updated and equipped with a brand new movement. This second-generation iteration marks the beginning of a new chapter for the Zeitwerk, with significant technical improvements to the model’s mechanics. Among the most exclusive and expensive releases from the brand, the Zeitwerk embodies refined modern watchmaking with a retro-chic flare.
The rework remains true to A. Lange & Söhne’s original design code for the watch, though its exterior is available in two novel and distinct materials. Externally, it opts for a 41.9mm wide case with a height of 12.2mm, available in either 18-carat pink gold or 950 platinum. At the 4 o’clock position on the case, the German maker has integrated a pusher that operates rapid forward adjustment of the jumping hour display that ensures easy correction between time zones. In keeping with the original design, the crown still rests at 2 o’clock.
The dial, available in either a black-colored or rhodium-plated solid silver depending on the case material, sports a familiar layout that remains consistent with the original Zeitwerk design. It includes jumping hour and minute apertures in the 9 and 3 o’clock positions, respectively, as well as a small seconds subdial at 6 o’clock. Towards the 12 o’clock position is a power reserve display; the detail remains in the same position as prior Zeitwerk models but includes the capacity to indicate the status of a much greater power reserve. Creating cohesion between each of the dial elements is a metal “time bridge” that matches the cool or warm tone of its respective case.
Powering the second generation Zeitwerk is the A. Lange & Söhne manufacture caliber L043.6. The movement allows for each numeral on the display to switch from one minute to the next until, as the hour changes, all three numeral discs shift by one increment at once. Two mainspring barrels and a “patented constant-force escapement” power and control the switching point respectively. As the biggest differentiator between this watch and its predecessors, the mechanism offers double the amount of power reserve at 72 hours.
