🔧 What it does & how to use

A pocket watch winding key engages the square winding arbor at the back of the movement to wind the mainspring by hand, since these older watches don't use a crown. This set is ideal for collectors, repairers and hobbyists who service or wind multiple pocket watches, as it removes the guesswork of sourcing a single key that happens to match. Each key is numbered for quick identification, so once you've matched a key to a watch you can note the size for next time.

• Identify the arbor: Locate the square winding arbor on the back of the pocket watch movement.
• Select a key: Starting from the smaller numbers, try each key until you find one that slides fully onto the arbor without slipping.
• Wind gently: Turn the key smoothly in the winding direction, stopping as soon as resistance builds to avoid overwinding.
• Note the size: Once matched, remember the key number for that watch for future winding.
• Store safely: Return keys to the box after use to keep the set organised and complete.

⚠️ Please check that you test keys carefully against the winding arbor before applying force — sizes vary between watches and an incorrect key can slip or mark the arbor.
