This is a good example of a Breguet pocket watch key.
These are keys which have an internal ratchet allowing wingding one way only and thus prevent you from winding a watch incorrectly.
The key has a large round handle and a suspension loop and ring.
The key has a silver coloured winding end and is a size 3-4
The key measures 34mm x 7mm x 4mm and is in 90% mint condition – excellent condition, just a little tarnished
