Lange & Söhne Zeitwerk rapidly became the new face of the highly respected German watchmaker vying for the coveted position of the Lange 1. Dubbed the "Time Bridge" crafted in German silver, the digital, simultaneous jump hour and minute display spans the length of the Zeitwerk's dial, with the subsidiary seconds ring at its center, making it a distinctly legible watch. To ensure the digital time display can switch all three-discs instantaneously requires exceptional engineering, incorporating the use of a constant-force escapement and remontoire.The Zeitwerk Striking Time released in 2011 in a limited edition platinum and non-limited white gold version is a truly technical marvel, not only able to cope with the complexity and power needs of a fully digital display, but incorporating a striking mechanism as well. The impeccable result can be appreciated in the present pink gold example with a solid silver dial that was only made available in 2014; a beautifully choreographed mechanical show of two polished hammers, striking the hour in a low-pitched tone on the left and the quarter hours with a higher pitched tone on the right. The striking feature can be set to silent through a small pusher at the four o'clock position.
