CHRONOMETRIC MECHANISM Russian patent published in 2007 - IPC G04F7/08 G07C1/28 

FIELD: clock-work industry, in particular, chronometric mechanisms providing for measurement of time read off beginning from a definite moment and controlled by pressing of a press button.

SUBSTANCE: the chronometric mechanism of the means for read-out of the chronometrized time has the first and second pinion chronometrizing mechanisms, each of them is designed for fixing the pointers that provide for indication of the first and second chronometrized time, and the coupling facilities have the first and second coupling devices intended for coupling of the finishing pinion mechanism respectively to the first and second pinion chronometrized mechanisms. The actuating means have a driving device made for engagement and disengagement of this or that coupling device, and a change-over device that is made for disengagement of the engaged coupling device and engagement of the disengaged coupling device.

EFFECT: enhanced accuracy of measurement of two events proceeding in the form of an alternating process.
