Initially launched in 2009 in pink gold, yellow gold, white gold and platinum – the latter as a limited edition – the Zeitwerk has become as emblematic of Lange as the Lange 1 or the Datograph. The introduction of the digital jumping hours and minutes display builds upon a 19th century patent by Josef Pallweber, though his concept displayed hours and minutes vertically rather than horizontally. Despite its apparent simplicity, the Zeitwerk’s time display mechanism is remarkably complex, requiring tremendous creativity to develop.

The bold “time bridge” framing the hour and minute apertures is crafted from solid German silver. The dial is a masterclass in balance, with the semicircular power reserve display at 12 o’clock counterpoised by the subsidiary seconds dial at 6 o’clock. Of note, the left side of the time bridge is secured by a screw, whilst the right side rotates on a jewel bearing, as the bridge is integrated into the movement. The stunning cal. L043.1 features a constant force escapement, lavishly finished with free-sprung Glashütte ribbing, mirror-polishing and delicate anglage.

This well-preserved example, offered along with its guarantee and accessories, in 18K pink gold presents an opportunity to acquire a landmark A. Lange & Söhne reference that shaped their modern collection.
