How does a mechanical movement work?

For those who may have forgotten, here is a quick refresh based on our 5401 movement in the course of assembly, and the six stages of the kinematic chain.

We illustrate this with our ultra-thin automatic micro-rotor Seed VMF 5401 movement

1. Energy source

Turning the winding crown or the wrist movements of the wearer provide the energy needed to operate the automatic mechanical watch..

2. Energy store

A spring wound in the barrel stores the energy for the operation of the mechanical watch.


3.   Counting, transmission 

A set of gears brings energy to the escapement.

4.  Distribution

The escapement transmits the energy to the balance, while counting its oscillations.


5. Adjustment

The balance and its spring determine the accuracy of the mechanical watch-

6.   Display

The speed of rotation of specific gears drives each hand at the correct pace.
