Description

Used by watchmakers and watch repair people, especially in the repair and working of pocket watches.  This is a quality set of pocket watch winding keys.  Brand is not marked, but it looks just like the set that Bergeon brands.  It is an old quality item, not the Chinese made garbage of more recent production.  

Winding keys are marked in the following sizes: 00, 0, 9,10,11, 12, and unmarked (the mismatch key is the unmarked one)
