Cadrature

Frame of the astronomical clock by Franz Zajizek (Vienna 1863–73)

The cadrature (also Cadratur or Kadraktur ) is an additional switching mechanism in complicated watches . It is the clock technology term for a modular mechanism for additional functions of clocks. It is a kind of intermediate gear to the movement , either inserted between the movement and the dial or, in the more elaborate form, integrated into the movement itself to enable further functions.

Cadratures are made by cadraturists .

Examples of frames are:

• Striking mechanism , for example as a repeater mechanism
• Alarm clock
• Musical mechanism
• Calendar work for displaying a calendar . The calendar is the corresponding part of the display, which is not responsible for displaying the time , but for the day , month , year , day of the week , moon phases, etc.
• Chronograph (stopwatch function of a clock)
