MECHANICAL PRINCIPLES

This chapter explores the mechanical principles governing the operation of a watch. From the energy stored in the Motor organ (power source) to its regulation by the regulating organ, discover the chain of the Movement, the many complications that enrich the Display, and the various Escapement systems that ensure the accuracy of timekeeping.

OPERATION OF A MECHANICAL MOVEMENT

The kinematic chain of the Movement, from the Motor organ (power source) that stores the energy to the balance-Hairspring (balance spring) that regulates it, passing through the transmission Train (wheel train) and the Escapement.

COMPLICATIONS

All the functions that are added to the Display of time: calendars, moon phases, Chronograph, chimes, time zones. The complications improving accuracy or providing indications of another kind.

TYPES OF ESCAPEMENT

Overview of the main horological escapements — Swiss lever, detent, duplex, cylinder and others — which convert the rotation of the train into regular oscillations.
