Renata Battery Tester (includes Mechanical Defect Test)
Watch Battery & Mechanical Defect Tester - Renata This practical tester helps you to test before opening the watch case, whether a stopped analogue quartz watch actually requires a battery change or if it is a mechanical defect that may be blocking the stepping motor, in which case, a repair rather than a battery change is indicated. If the watch hands are not moving, place the complete watch on the centre position to hear the pulse of the watch. Plus complete testing of batteries.
