    Default Zeroing the Chronograph

    I purchased a Ball Trainmaster Pulsemeter Chronometer Chronograph - the Chronograph seconds hand will not reset to zero. Does anyone know how to zero out a Ball Chronograph? User manual is silent on this. Any help appreciated

    I believe your watch has the Valjoux/ETA 7750 movement. If so, have a look at this site for instructions on the movement. That said, I'm not aware of any procedure to reset the 7750 so it zeroes properly. My guess would be that the hand is slipping on the pinion and will likely need to be replaced which means (unless you are competent with watch movements) sending it out for service work.
