Leroy demonstrates the full measure of its expertise with the Automatic Tourbillon Regulator. A large flying tourbillon freely orbits at its summit, unobstructed by any bridge. Its heart is in diamond with an openworked structure.
The pure technique behind this regulating organ ensures a degree of precision that is certified by Besançon Observatory. The entire movement, oscillating weight and dial of the Automatic Tourbillon Regulator have been delicately skeletonised and chamfered by hand. A meticulously fashioned rosette, with echoes of the early 1900s, adorns the off-centre hour dial, signalling the regulator configuration of this seven-piece limited series. Hand-finishing extends even to the heat-blued slender hands. Leroy respects the elegance and ornamentation of French style, matched by peerless standards of precision.
