How does a mechanical alarm clock work?
To make a mechanical alarm clock work, you need to use the wind-up keys or buttons to set the time. Mechanical alarm clocks use an oscillating wheel and springs. Most mechanical alarm clocks come with two bells that ring by means of a gear, powered by the mainspring. The gear moves quickly between the two bells, sounding the alarm.
