Notes
Although it is signed "Breguet ", and devised with a male square to
wind watches with female winding square, this key is very similar to
that illustrated on Tavernier ' s own advertisement. It was certainly
produced by Tavernier at the request of Breguet.
A reproduction of the original instructions supplied by Tavernier
for such astronomical keys, is published by Mathieu Planchon in
