A. Lange & Söhne Zeitwerk Minute Repeater

The year's major innovation, the Zeitwerk Minute Repeater is the first Lange watch with a decimal repeater, sounding the hours, ten-minute intervals and minutes. The chimes, which are actuated by a pusher, always correspond to the time shown on the dial. If the striking mechanism is triggered when a numeral or numerals are about to change, the jumping action of the discs is delayed until after the chiming sequence has finished. As a safety precaution, the crown cannot be pulled out to set the time during the chimes. Furthermore, the striking mechanism will not operate with less than 12 hours of power reserve. http://bit.ly/1NejoUp
