🔧 What it does & how to use

These keys are for manually winding pocket watches that need a separate winding key rather than a crown, and they're handy for repairers and hobbyists working on a range of vintage movements where stem sizes vary. Each key is stamped with its size number so you can quickly find the right match rather than forcing an ill-fitting key onto the arbor.

• Check the stem: look at the winding arbor on the movement and compare it against the numbered keys to find the closest fit.
• Fit the key: slide the square socket end fully onto the arbor so it seats squarely and isn't at an angle.
• Wind gently: turn slowly and stop as soon as you feel firm resistance — never force it past the point of resistance.
• Keep the set together: store both keys as a pair so you always have the full size range on hand for future repairs.

⚠️ Please check the size numbering against your own movement's arbor before winding — using a key that doesn't seat squarely can slip or damage the stem.
