Abstract (en)
[origin: EP1795976A2] The watch has a constant force device for admission of oscillating systems. A switch gear unit (9) of the constant force device is provided for periodically controlling clamp of a secondary spring brake of clamping modules of the constant force device by a primary spring brake forming a barrel. The periodic controlling of the switch gear unit takes place by a cam plate (16), which is permanently and rotatably driven. A secondary shaft (18) is rotatably driven by the secondary spring brake. The shaft carries the cam plate and the secondary wheel driving the oscillating system.
