We have developed a minute repeater mechanism based on the SPRING DRIVE movement. Within the limited dimensions of a movement, we have increased the duration time to a maximum and moreover, we have founded the means shown below in order to avoid the troubles caused by wrong operations of users. 1. By the means of two main spring barrels placed in series, we have increased the running time of the watch. 2. By modifying the minute repeater mechanism and turning it into the Sonnerie center wheel, it was possible to remove the minute repeaters spring and draw the mechanical energy directly from the main spring barrel. 3. While the minute repeater mechanism works, if the lever that releases the center wheel is used, the crown cannot be pulled out because it is equipped with a security system in order not to activate the minute repeater when the crown is in "pull out" position.
