A. Lange & Söhne's Zeitwerk Minute Repeater is the first mechanical wristwatch with a jumping numerals display and a decimal minute repeater.

The timepiece's acoustic time indication corresponds exactly with the jumping numerals reading. As soon as the striking mechanism is activated with the button at 10 oʼclock, the gong hammer on the left strikes the hours, the one on the right the single minutes. For the double-tone ten-minute intervals, both hammers strike the gongs slightly offset in time.

The manufacture has released a new version in 18K white gold, with a striking blue dial.
