Esslinger & CoPocket Watch Key Assortment Set 14 Sizes 00 - 12 Winder Tool for Pocketwatch Kit

If you have an old key wind pocket watch and you're missing the key, then you need this set. If your watch is from an American manufacturer, then one of these keys will fit. All of the key sets that are offered by different merchants appear to be the same so I would just buy based on price.

I thought product was different than what it was. I returned product because I no longer needed it and it did not fit.

My set was missing Key #7, but #6 seems to work in my pocket watch.
