A dividing head or division plate is a disc or plate that contains a series of evenly spaced holes or notches that correspond to specific divisions of time, such as minutes or seconds. It is typically used in conjunction with other tools and machinery in watchmaking to accurately set and adjust the timing functions of the watch. By aligning the appropriate hole or notch with a reference point, watchmakers can ensure precise division and synchronization of the watch's timing mechanism, allowing for accurate measurement and display of time.
