A. Lange & Söhne. A very fine 18K pink gold jump hour and minute wristwatch with power reserve

The first timepiece by Lange incorporating digital indication of hours and minute, the Zeitwerk is among the most appreciated and unusual timepieces by the German manufacturer. In a nod to the oversized date display Lange is famous for, the time is represented in a similar oversized digital style delivering what can arguably be considered the most easily readable time display in modern watchmaking. From a technical point of view, the movement powering this piece is a true feat of engineering: instead of slowly and continuously revolving as it is often seen on digital timepieces, the discs jump instantaneously. This is due to a remontoir which stores energy over the course of a minute to deliver a burst sufficient to have the disc jump.
