Chronoswiss emphasizes once again how fascinating mechanics can be on the Régulator à Tourbillon Squelette--the first tourbillon to be displayed on a skeletonized Régulator dial. Expert watchmaker Gerd-R. Lang in association with Marc-Aurele Rochat, grandson of the founder of Vallée de Joux, where skeleton art began, succeeded in paring away enough of the dial to reveal a masterfully filigreed, fully functional clockwork. The tourbillon's cage completes a rotation around its own axis every 60 seconds. The classical balance, balance-spring, and escapement (developed originally by Abraham-Louis Breguet in 1801) all rotate along with it, thereby outsmarting gravity and ensuring that time never strays out of equilibrium. The Chronoswiss Caliber C.361 S manual-winding mechanism is housed inside a 19-piece red gold case and fitted with non-reflective sapphire crystal, screw-on bezel, and screw-on turnip crown. Two spring barrels maintain working power for up to 72 hours. Upon the skeletonized sterling dial, a blued steel poire (pear-shaped) minutes hand is centre-mounted and the hours hand delivers its plot from beneath the 12. Wear it on a Louisiana crocodile leather strap with tang buckle. Technical progress is indicated by the cantilever tourbillon cage pivot-mounted on a ball bearing and a balance frequency of 28,800 semioscillations per hour to stablize the working. Other features include bottom plates pearlized on both sides and bridges adorned with Genevan striated finish. Angled and polished edges, blued screws, and three screw-mounted gold settings complete the stunning ensemble.
