Will someone please explain to me how people used these? Is it true that they didn't require an electrical cord OR batteries?

Spoiler Warning...
Palouday: Mechanical alarm clocks worked similarly to how a mechanical music box works. You wind a spring inside that gets tighter and tighter, which is what produces the energy to make the clock run (hence why it slows before it stops). This energy is used to turn the various gears inside the clock, which move the hands around the clock face, telling you the time. The alarm functions on another attached set of gears and spring, which are connected to the hour hand. When the hour hand reaches the set time, a lever is released and the energy in that spring is conveyed into the bells at the top of the clock, which will rattle until you click the button to reset that lever or it runs out of energy.

Thanks! I knew they didn't need electricity but I'd never read a description of how they worked.

Am I the only one who thinks it looks a little surprised at the time?
