DEVICE COMPRISING A MOVEMENT FOR A TIMEPIECE AND A CHRONOGRAHIC MODULE

摘要

A device comprises a base movement (MB) for a timepiece the time display of which is driven by a first barrel connected to a first mechanism and a first regulator and an autonomous chronographic module the time display of which is driven by a second barrel independent of the first and connected to a second mechanism and a second regulator. The chronographic module is exclusively comprised of mechanical components. The oscillation frequency provided by the regulator thereof is equal to N times the oscillation frequency for the regulator of the base movement, the coefficient N being able to be defined as a function of a specific application for the chronograph, such that any chronographic module as previously defined may co-operate with the same base movement. The chronograph regulator is constantly engaged with the corresponding mechanism. The chronograph module permits the reading of a time interval with a minimum precision of one hundredth of a second.
