Movements in Watch Wiki

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

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.

• The winding mechanism provides the drive with power.
• The dial train serves the coupling of the time indication components.
• The hand setting mechanism serves the setting of the correct time.

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.
