The Count Wheel (Locking Plate) is an important part of a mechanical watch movement, which helps to control the rate at which the gears turn. It is a disk-like shape made of metal with a series of round holes in it. These holes are connected to a spring, which is held in place by a locking plate. The spring pushes against the count wheel to ensure that the gears turn at a steady rate. The count wheel is essential for ensuring that the watch keeps accurate time.
