Complicated mechanisms refer to all the complex mechanisms that can be found in a watch movement. By definition, they are distinguished from watch complications that display or signal additional temporal information.

For example, the most basic way to display the second is to place the second hand directly on the axis of the fourth wheel. Thus it is off-center, usually at 6 o’clock and is called “small second”. Placing this hand on the central axis of the hours and minutes can be considered a complicated mechanism.


Tourbillon is a mechanism that neutralizes the negative effects that gravity can have on the regulation of a mechanical watch.


Resonance is a mechanism where two oscillators, pendulums or balances, are placed very close to each other and thus resonate in order to increase the accuracy of the timepiece.


Retrograde display is a mechanism where a hand does not rotate 360 degrees, but is placed on a circular arc and returned to the beginning after a certain angle is covered.


HOROPEDIA is a participative knowledge platform and we invite all those who wish to contribute to this adventure of sharing watchmaking knowledge to join us.

It can be additional explanations, images or other illustrations or terms not yet identified that deserve to be.
