Two watches in one.
Thanks to its patented dial which turns from black to transparent, the Revelation R04 Tourbillon Magical Watch Dial - that will be presented at BaselWorld 2013 - can unveil the in-house tourbillon movement by simply rotating the bezel.
This innovation is possible thanks to the superposition of two polarising discs whose nanostructures play the role of shutters. In order for the discs to play their “on/off” role, they must be placed on top of each other and be able to pivot.
Their nanostructures will either block the light or let it pass through to the movement depending on the rotation of the bezel upon which one of the polarising discs is mounted.
In collaboration with the optical department of the Swiss Center for Electronics and Microtechnology (CSEM), Revelation obtained the specific surface structures for the polarising discs in order to achieve the best possible transparency in the open position while ensuring maximum opacity in the closed position.
When the R04 Magical Watch dial bezel is rotated 90 degrees, a novel watchmaking calibre appears: the Tourbillon Manege. It was named "manège" by the Revelation watchmakers, because just as in a fairground attraction or carousel, where cars and horses are mounted on a rotating platform, all components of the regulating system such as the balance, lever, wheel, and its escape pinion are mounted on a mobile arm: the Tourbillon Manege bridge.
This platform is held between two wheels that are mounted on the central axis of the piece. This system transmits the force supplied by four barrels through a conventional going train. The wheel torque maintains the rotation of the Tourbillon Manege, which has been calculated to last one minute, thereby compensating, just as in a traditional Tourbillon mechanism, for gains or losses in rate.
Thanks to its four series-coupled barrels, this manufacture hand-wound movement offers a power reserve of 48 hours.
The R04 Magical Watch Dial is currently available in 18kt pink gold with the case middle and back cover in black PVD-coated titanium. Diameter of the case is 45 mm while thickness is 15 mm. The watch is water resistant to 30 mt.
This model is offered with a black rubber strap with a black PVD-coated titanium folding clasp.
