In today’s video we compare two different approaches illustrating the constant force mechanism and we not only do so with our good friend Peter Speake but with two great timepieces coming from Ferdinand Berthoud and the second one from Arnold & Son. Peter comes back on what is constant force and details with us how it has been expressed differently on these two timepieces.
If you want to see the deconstruction of both these timepieces made by Peter, here are the links:
