Video. Zeitwerk Minute Repeater: The decimal minute repeater mechanism

This films explains us the principle of the decimal minute repeater mechanism developed by A. Lange & Söhne.

The Zeitwerk Minute Repeater is the first A. Lange & Söhne model with a striking mechanism that sounds the hours, ten-minute intervals, and minutes.

When they developed the strikework for this watch, the engineers harnessed the principle of the jumping numerals mechanism: instead of with hands, the time is displayed with an hour ring and two minute discs. This allows three snails connected with these mechanical display elements to separately sample the number of hours, ten-minute intervals, and minutes to be acoustically indicated.
