Inside every second.
How does a wound spring become a ticking watch? These four parts control how its energy is released.
Release.
The escape wheel and pallet fork act as a gate. Together, they are called the escapement. Each release gives the balance a small push.
Repeat.
The balance and hairspring repeat a steady back-and-forth motion. This model makes four complete cycles per second: eight beats, or ticks.
