System for securing a balance spring

A device () for resetting to a predetermined position an indicator member () indicative of a parameter connected with time, notably a 'flyback' device, the indicator member being kinematically linked to a drive mobile (), the device comprising an energy accumulator () and a return element () for returning the indicator member indicative of the parameter connected with time to the predetermined position, the return element being powered by energy from the accumulator, the energy being supplied to the energy accumulator by a user via a control member () for resetting to the predetermined position, the control member being able to be manipulated by the user.
