2013 sees the introduction of new developments on the Tourbillon Double Spiral calibre, including the mastery of its escapement mechanism.

Laurent Ferrier wished to optimise the efficiency of its calibre by enhancing the reliability of the regulating organ. The Research & Development department worked for the last 15 months on improved energy management. It devised a new geometry for the lever, for which a patent has been filed, as well as of the escape-wheel in order to provide them with constant support. This approach reduces the losses of force due to backlash and facilitates the unlocking impulse, while the existing energy is used in a more efficient manner. The balance has also been redesigned in order to perfect its rating accuracy. Together with the double balance-spring tourbillon mechanism as well as manual adjustment, the regulating organ of this chronometer thus maintains excellent rating regularity.

A new calibre naturally called for new dials. Crafted in silver-toned or slate grey 18K gold, they highlight the beauty of manual decoration, with a central “Clous de Paris” guilloché motif and a circular satin-brushed surround. Once again, concern for detail has been taken to extremes, a signature characteristic of watches by Laurent Ferrier.
