A-ha! That is the trick question for the cats - what is a pendulum and what is not?
Here is a unique Calabrese-Kazes collaboration.
It is an interesting "pendulum tourbillon escapement" to cock-a-snook at certain other tourbillon makers' definitions of what is a true 'tourbillon'. The more horologically aware will explain better than I could with the close up photos below.
Remember that Calabrese invented the minimalist Golden Bridge movement, elements of which, are used by CORUM.......
