A timepiece that worth at least RM1,252,192.00 :
Jaeger LeCoultre's Reverso-Gyrotourbillon-2
- the three-dimensional spherical tourbillon has got two carriages rotating in 2 different speed, the inner one completing a full turn in 18.75 seconds, while the outer one performs a more conventional one-minute turn.
- 36 x 55 x 15.8mm , 371parts.
- Cylinder-shaped balance-spring, invented by English watchmaker John Arnold, who had it patented in 1782. this ingenious discovery which guarantees a regular and perfectly isochronous development of the balance-spring was reserved exclusively for marine chronometers and a few generously sized pocket-watches. It thus appeared doomed never to drive a wristworn mechanism. Innovative watchmakers chafed at this regrettable situation, since its rating characteristics are unanimously considered to be infinitely better than those of a flat balance-spring.
- Spherical tourbillon, 1st unveiled in 2004 ,composed of two carriages mounted on axes set at a 90° angle, this horological microcosm is still the only mechanical device enabling a wristwatch to break completely free from the detrimental effects of gravity on its timekeeping precision.
~ 0.34 grams to escape the law of gravity ~
