Screw-back watch back opener

Quicktest

£5

For removing the backs of watches that screw on (screw-back). These are small and portable, ideal for antiques dealers and anyone who travels around. You could, however, struggle getting enough leverage to open 'stuck' watch backs. STANDARD 2.5 inches X 1 inch. Minimum watch back size 15mm. Maximum watch back size 55mm. The prongs are 'hooked' as shown in top picture. JUMBO 3.25 inches X 1.5 inches. Minimum watch back size 23mm. Maximum 70mm (that's large!). The prongs are 'round' as shown in the picture.
