First Magnetically Secured Pivots in a Movement: Breguet Classique Chronométrie Ref. 7727:
Th is research into what could be the use of magnetism in a wristwatch movement began under the tutelage of Nicolas G. Hayek himself and was first seen at Baselworld 2011, just after his passing, in the grand complication timepiece that may well be the best tangible example of his life’s work when it’s done.
Meanwhile, we are allowed to glimpse bits and pieces of the new technologies being developed under the Swatch Group’s cloak of secrecy little by little, beginning with the patented invention that harnesses the power of magnetism to prevent shocks to the watch (such as dropping it) from influencing accuracy. In this timepiece, pivots are held in place by a magnetic field.
According to Mark Hayek, it is this potential (and now tangible) use of magnetism that has prompted research into and use of silicon in the escapement as this material—in stark contrast to traditional metal materials—may not be influenced by magnetic fields. “I dream and hope that it might even be something that is bigger than Breguet one day and will be used in other mechanical movements,” Hayek admitted during Baselworld 2013. “We’d like to protect it as long as we can, but it is potentially something [similar to the] Breguet overcoil, used [by the whole industry] after [the patent runs out] in movements. I think this has the potential to be something like that, and that’s the biggest compliment that can happen to Breguet, but it might be after [my time].” ED
