The Second Generation of the Digital Watch with a Mechanical Heart
Lange presents two new versions of its award-winning mechanical digital watch, first introduced in 2009, in platinum and rose gold. The calibre L043.6 has seven patents.
For the Zeitwerk, the master watchmakers at A. Lange & Söhne took their inspiration from the famous five-minute clock at the Semper Opera House in Dresden. At the time, court clockmaker Johann Christian Friedrich Gutkaes was commissioned to create it. He was asked to develop a time display that would be easily legible even from the rearmost seats. It was a challenge that forced Gutkaes to rethink the assignment. Contrary to all large-format clocks with hands, he opted for a revolutionary solution: a clock that displayed the time digitally in five-minute steps. In 1841, he completed the five-minute clock with his co-worker Ferdinand Adolph Lange. The unusual idea behind this clock was transposed to the Zeitwerk, even though it switches five times more often than its source of inspiration, namely once per full minute.
The case, in platinum or in 18kt rose gold, measures 41.9mm x 12.2mm. It has double sapphire crystals.
