A. Lange & Sohne Zeitwerk Minute Repeater

A. Lange & Sohne Zeitwerk Minute Repeater is the first Lange watch to combine  jumping time displays for the hours and minutes with a 10-minute interval repeater. The simple, legible dial belies the complexities of the movement and its chiming mechanism https://www.captainthewatch.is

Since the time can be read quickly (jumping hours are displayed in a window at 9 o’clock, minutes are on two discs of different heights at 3 o’clock, and small seconds at the bottom of the dial), the wearer can then turn his attention down to the bottom of the dial, where the two black-polished steel hammers for the minute repeater are readily visible on either side of the seconds subdial. When the pusher at 10 o’clock is pressed, the hammers strike the gong encircling the dial.

The hours hammer, with a lower pitch, is on the left side; the higher-pitched minutes hammer is on the right. Ten-minute intervals are signaled via a “double tone”: the higher pitch is hit with the lower one immediately following. The maximum duration it takes to strike out the time (at 12:59) is approximately 20 seconds.
