Patek Philippe form movement 28-20/220, the first mechanical movement with a power reserve of more than 10 days worldwide

Patek Philippe form movement 28-20/220, the first mechanical movement with a power reserve of more than 10 days worldwide.

The Watch Movement

A movement essentially consists of the following three functional groups:

  • The power source supplies the movement with energy, so that it moves.
  • The gear train (transmission) serves for the revolutions increase (1 revolution per hour, per minute) and thus for the force reduction.
  • The escapement restrains the operational sequence of the train.

Further function groups are the winding mechanism, the motion work and the pointer servo unit.

Additional functions: Depending on the additional function of the movement or the watch there are more function units integrated. These include:

  • A movement with alarm function generates a tone at a previously set time.
  • The carillion announces the time with acoustic signals.
  • The calendar shows different informations depending on the date.
  • The chronograph movement allows the measurement of time intervals.
  • The automatic winding converts the kinetic energy of the wearer of the watch into mechanical energy to drive of the movement.
