A striking clock is a clock that sounds the hours audibly on a bell, gong, or other audible device. In 12-hour striking, used most commonly in striking clocks today, the clock strikes once at 1:00 am, twice at 2:00 am, continuing in this way up to twelve times at 12:00 mid-day, then starts again, striking once at 1:00 pm, twice at 2:00 pm, and ...
Both the third quarter and the full hour require the fourth quarter bell, B 3, to be rung twice in quick succession (changes 4,5,1 and 2,3,4,5); too quick for the hammer to draw back for the second strike.

The first repeaters had a single bell mounted in the back of the case, on which 2 hammers would strike. This bell was made of "Bell metal", a mixture of copper and tin. Later repeating watches use gongs made of long hardened steel wires that are coiled inside the watch case. Tiny hammers actuated by the repeater mechanism strike them to make ...
