A clockwork movement includes a control member actuatable by a control lever in response to a user's action and having the form of a column wheel. The control member is rotatably mounted on the clockwork movement frame around an axis X, perpendicular thereto, for controlling first and second mechanisms exhibiting at least one movement function such as chronograph or alarm function. The control member includes rotationally fixable first, second and third parts which are mounted on a shaft at first, second and third levels, respectively, in a direction of the axis X for interacting with the control lever and for controlling the mechanisms. The shaft which is pivotally mounted with respect to the frame is arranged in at least two bearings, which are positioned remotely to each other for ensuring the shaft good stability, whereas the second and third parts are located on the both parts of the frame.

Clockwork movement

A chronograph clockwork movement for measuring time includes a control lever actuatable by a first control member for alternatively activating or deactivating a time measurement, clutch elements for driving or not a second timer in response to an action produced on the control lever and selective locking members for locking the second timer in response to an action produced on the control lever. A lever and a hammer for resetting the second timer to zero are also provided. The clockwork movement is arranged in such a way that a user does not feel any difference, while measuring a time, whether the second timer is pre-set or not. The clockwork movement has a structure enabling to activate time measuring by delaying the effective departure of the second timer until an external resetting device controlling the lever is released in the rest position thereof.

Time piece chronograph clockwork movement

A clockwork movement hammer () is used for interacting with heart-shaped cams () provided with corresponding axes of rotation () which are positioned remotely to each other. More precisely, the hearts () are connected to a chronograph timer, whereas the hammer belongs to the resetting mechanism of the chronograph timers. The inventive hammer () includes at least one first part () movably mounted on the clockwork bottom plate () and one second part () bearing supporting surfaces () which can be bring into contact with the hearts () . The two parts () of the hammer () are connected to each other by at least one swivel-type connection () for making it possible to adjust the corresponding positions of the supporting surfaces () while a resetting process. Due to particular characteristics thereof, the structural design of the hammer () is simple and small-sized.
