JLC - Master Hybris Inventiva Gyrotourbillon À Stratosphère - Limited Edition - 42 MM - Platinum - Blue Enamel Guilloché Dial - Black Alligator Leather Strap - Q5306480

The Master Hybris Inventiva Gyrotourbillon À Stratosphère, limited to 20 pieces, is part of a long line of inventions nurtured by Jaeger-LeCoultre’s pursuit of precision, which began almost two centuries ago. The triple-axis tourbillon construction of Calibre 178, for which several patents have been filled, takes the multi-axis tourbillon construction even further, to become a tourbillon within another tourbillon within yet another tourbillon. The kinematics of this triple-axis tourbillon achieves 98 per cent of all possible positions to compensate for the negative effects of gravity on the precision of the watch.

On the front of the watch, the 18K white gold movement plates are decorated with sunray guilloché and then coated with translucent blue enamel. The visible hollowed-out 18K white gold bridges are filled with blue lacquer to match the design, and even the covers of the two large spring barrels – unmistakable from the dial side at approximately 2 and 10 o’clock – are engraved and hand-lacquered in the same blue.

Ensuring high precision, the manually wound Calibre 178 beats at 4 Hz (28,800 vph) and offers a remarkably long power reserve of 72 hours. The owner can monitor the current state of winding thanks to the discreet 18K pink gold power reserve display on the back of the calibre, indicated by a long, thin gold hand.
