🔧 What it does & how to use

A precision screwdriver for the fine slotted screws found in watch and clock movements, cases, bracelets and straps — used for servicing, battery changes, strap swaps and general repair work by both hobbyists and professional watchmakers. Matching the blade width exactly to the screw slot is essential to avoid slipping and marking the screw head or surrounding case.

• Choose the size: pick the blade width that matches the screw slot as closely as possible
• Steady the work: support the watch, case or bracelet firmly, ideally on a case cushion or holder
• Insert the blade: seat it fully and squarely into the screw slot before applying pressure
• Turn to loosen or tighten: apply gentle, even pressure — let the blade do the work rather than forcing it
• Check the fit: if the blade rocks or slips in the slot, switch to the nearest size for a snugger fit

⚠️ Please check you're ordering the correct blade width for your screw before buying, as this is a single screwdriver sold in one size only — an incorrect width can slip and damage the screw slot.
