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.

The harmonious construction and the technical performances of the Square Micro-Rotor are part of a global approach envisaged for each of the movement parts, aimed at optimizing energy management – the ultimate goal being to improve user friendliness by more efficient automatic winding of the movement.
