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

RESONANCE
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
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.
