In a mechanical movement, the gear train is part of which system?

The gear train is an integral part of the transmission organ in a mechanical movement. It serves to transfer energy from the mainspring, which is responsible for powering the watch, to the escapement and other components that allow the watch to keep accurate time.

Within the transmission organ, the gear train comprises various gears that work together to reduce the high-speed rotation of the mainspring into controlled rotations suitable for the escapement system. This controlled energy release is crucial for maintaining the accuracy of timekeeping.

In summary, the gear train's function is primarily to manage the flow of energy and build the necessary torque required for timekeeping through its role in the transmission organ, making it an essential component of the mechanical movement.
