🔧 What it does & how to use

This tool is designed to remove screw-on watch case backs, most commonly needed for battery replacements and general repairs. The adjustable three-claw head expands or contracts to grip the notches or slots on the case back, and turning the handle unscrews it from the watch body. It comes with 4 sets of clamps to suit different case back designs, giving good coverage across many watch types. Simply select the matching clamp set, fit it to the claws, centre the tool over the case back, apply light downward pressure to keep the claws engaged, and turn to unscrew. Suitable for hobbyists and watch repairers alike, and stored neatly in the supplied plastic box when not in use.

⚠️ Please check your watch has a screw-on case back (rather than a snap-fit or push-on back) and that one of the 4 included clamp sets matches the notch pattern before use.
