Its calibre that is automatically wound by means of an off-centred Micro-Rotor, stems from an exclusive development inspired by the “natural” escapement invented by Abraham-Louis Breguet. This new double direct-impulse escapement fitted directly on the balance is equipped with a silicon lever. This modern construction, combined with the use of cutting-edge materials, maximizes energy efficiency, which in turn ensures high amplitude for the balance and reduces the mechanical force required to wind the mainspring.
