Abstract
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.
