In a mechanical wristwatch with a simple chronograph, what component transmits information given by the pushers?

In a mechanical wristwatch with a simple chronograph, the column wheel acts as a central component that facilitates the transmission of information from the pushers. When a pusher is activated, it engages the column wheel, which is designed with various notches and positions that correspond to different functions, such as starting, stopping, and resetting the chronograph.

As the pushers are pressed, the column wheel rotates to the appropriate position, translating the linear motion of the pushers into the necessary rotations or movements to operate the chronograph functions. This ensures that the chronograph can be effectively controlled, allowing for accurate timing.

Other components, such as the gear train, pallet fork, and hairspring, have crucial roles in the overall functioning of the watch, such as regulating timekeeping or transferring energy, but they do not directly manage the interactions initiated by the pushers in relation to the chronograph features. This makes the column wheel the correct component associated with the pushers in a mechanical chronograph setup.
