Abstract
This timekeeper comprises a first timer (), means () for connecting it selectively to the train of the timekeeper (T), a second timer (), a synchronous coupling between the first () and second () timers, and fly-back means () for said timers (). An auxiliary motive source (') is in a driving relationship with the second timer () and a one-way coupling () is situated between the first () and second () timers to regulate the speed of movement of the latter at a predetermined ratio with the speed of movement of the first timer () while allowing one-way relative movement of the first timer () relative to the second () when the latter is in the stop position and one-way relative movement in the opposite sense of the second timer () when the first timer () is in the stop position.
