JEAN DUNAND - Tourbillon Orbital


















JEAN DUNAND - Tourbillon Orbital



The Tourbillon Orbital features an extraordinary one-minute flying tourbillon that orbits the dial once per hour on a patented revolving movement, a novel power reserve indicator in the case band and moon phase on the caseback.

Visually sublime, the Tourbillon Orbital is a masterpiece of haute horlogerie. Timing tests indicate that the combined rotation of the tourbillon and the movement significantly improves the rate stability of the watch.

Here the rarest and most unexpected materials, anachronistic craftsmanship and unheard of complications find a place to flourish far from commercial pressures and the noise generated by the machines of mass luxury.

It took Christophe Claret two years to solve the challenge of winding and setting a constantly rotating movement and mainspring barrel with an innovative folding key set vertically into the movement’s central axis that both winds the mainspring and sets the time.

The absence of a crown facilitated a fascinating lateral view of the revolving mechanisms through two windows in the case band. The secret of statically indicating the power reserve of a constantly moving barrel is patented, while the dial is a revolving canvas displaying the world’s best art, craft and natural materials.

As with every Jean Dunand timepiece, each Tourbillon Orbital is a unique piece.

                                                     TOURBILLON ORBITAL
                                       WHO SAID “IMPOSSIBLE”?


Launching the family of JEAN DUNAND watches, a continual pro-gram of Pièces Uniques, required something more than a mere aes-thetic fillip. The watch had to be fresh, original, groundbreaking. At a time when watch connoisseurs are spoiled for choice, a watch com-memorating the great Art Deco artist and craftsman had to be heart-stoppingly beautiful and daring.

That honor fell to the Tourbillon Orbital, the first of JEAN DUNAND timepiece and an achievement never before seen in watchmaking. It features a one-minute flying tourbillon that orbits the dial once every hour, on a revolving movement. The watch also introduces a novel power-reserve indicator in the case-band, provides a full view of the movement and displays the phases of the moon on the case-back.

So extraordinary is this movement that it is patent-protected.

With every ambitious watchmaker jumping on the tourbillon “band-wagon”, it is not surprising that some enthusiasts are voicing a back-lash. Strange though this may seem, the sheer profusion of lesser tourbillons has rendered the complication almost “common”. Thierry Oulevay and Christophe Claret, however have too much respect for the concept to allow it to be devalued.





























To this end, they have created the IO200 movement, named after Ju-piter’s moon. Invented and constructed by Claret, it defies the opin-ion of his fellow watchmakers who insisted that an orbiting tour-billon was impossible to realize. It is a gauntlet thrown before the most experienced houses. Furthermore, it returns the tourbillon to its original role as the pre-eminent precision complication. Timing tests prove that the combined rotation of the tourbillon and the movement significantly improves the rate stability of the watch.

                                          Wheels within wheels

Positioned opposite each other, sandwiched between two plates held apart by pillars and rotating on ball bearings, the barrel and the flying tourbillon orbit the center. The revolving top plate is open to reveal the tourbillon. The tourbillon has been raised as much as possible to make it more clearly visible.


Unwinding against a central fixed pinion, the barrel drives itself and the tourbillon, while the tourbillon escapement regulates the speed of rotation. As it orbits, the tourbillon cage rotates once a minute against a fixed circumference wheel, connected through a gear train. This elegant configuration reduces the number of jewel bearings to 14, substantially lowering friction.


                                     How to wind and set a rotating movement

Christophe Claret  devoted two years to solving the mechanical chal-lenge of winding and setting a rotating movement with a mainspring barrel that never stays in one place. The conventional crown through the case-band was obviously impossible.

Winding and setting the movement vertically through its central axis is a new solution in watchmaking. A folding key set into the case-back replaces the crown. Lifting the D-ring of the key engages a central wheel on ball bearings that turns the ratchet-wheel to wind the bar-rel-spring. Pulling out the key engages the hours- and minutes-hands in order to set them in any direction. Positioned against the fixed chapter-ring, the minutes-hand turns with the rotating dial.

                                   Windows to the heart of the movement

Inescapably, the winding key and the moon-phase display on the back of the watch prevent a conventional view of the rotating movement through a sapphire-crystal case-back.

Conveniently, though, the absence of the usual crown at 3 o’clock allowed JEAN DUNAND’s case-makers to provide a fascinating lat-eral view of the revolving mechanisms by cutting two windows in the case-band.

                                A power-reserve indicator never seen before

These side windows opened the opportunity for another first in watch-making – an entirely original way of indicating the power reserve. The window at 3 o’clock displays a vertical needle that moves between

F (full) and E (empty). Precisely in the manner of fuel gauges in vintage cars. The secret of indicating the power-reserve in one place from a constantly moving barrel is patented.
