The cliquetCliquet The cliquet ('Click') is a small metal component in a mechanical watch movement that serves as a ratchet, it prevents the mainspring from unwinding in the wrong direction. It works by locking the barrel arbor when the mainspring is being wound, and releasing it when the watch is running.

It is located inside the barrel. The mainspring is wound, either manually or automatically. The mainspring unwinds over time, and the watch will stop running when the mainspring is fully unwound.

It works by locking the barrel arborBarrel Arbor In a mechanical watch movement, the barrel arbor is a shaft that runs through the center of the mainspring barrel. The mainspring is wound around the barrel arbor, and as the mainspring unwinds, it powers the watch's movement by transmitting torque through the gears of the movement.
