We hear the chimes while the locking lever is sliding around the edge of the quarter count wheel. At that moment, driven by the descending weight, the drum unwinds and sets in motion the hammers of the quarter bells that are attached the clock mechanism by pull-wires. The bells weigh 37 and 58 kilogrammes. During the chimes one bell sounds a little after the other. A single double chime indicates the first quarter, two the second and so on. When the locking lever reaches the next groove on the count wheel, the chiming mechanism is halted.
