In the heart of the de GRISOGONO OTTURATORE there beats an unusually complex mechanism. Besides the traditional hour and minute hands in the center, the watch displays on demand the seconds, date, phases of the moon and power reserve. The zest of the timepiece is the selective display of each of the discrete indications mentioned above.
As you know, classic watches usually feature all their complicated functions together on the dial, and the created conglomeration of indications seriously affects the watch's instant legibility. Fawaz Gruosi pioneered another approach, having simplified the dial layout to come up with much enhanced legibility.
Innovative Sequential Display Selector
Mr. Gruosi developed an absolutely original, mechanically driven sequential display selector. The OTTURATORE watch has incorporated a mobile dial that allows the wearer to choose the indication he wants the watch to display at the moment - seconds, date, phases of the moon or power reserve, the three other indications are hidden from view. The high-performance mobile 'sequencer' patented by de GRISOGONO has been developed with help of simulation and numerical calculations.
The increment of rotation of the de GRISOGONO OTTURATORE is 90 degrees. Based on the principle simple enough, its design is absolutely unprecedented, transferring watchmaking technology from the realms of slow speeds to hyper velocities.
A gentle pressure on the push-pieces - whose travel is of the order of one millimeter - harnesses enough power to drive the mobile dial (or sequential selector) by 90 degrees in a few dozen milliseconds! Compare it with triggering a mechanical chronograph that takes hundreds of milliseconds.
In case of a usual mechanical construction, pressing a push-piece for an instant does not exert enough power to set in motion mechanical components with strong inertial resistance. Just in a few dozen milliseconds, the OTTURATORE's sequential selector can action fifteen dynamic functions, including controls, connecting and disconnecting operations, mechanical memory, gears, etc, while considering power drain, inertia and friction. The sophisticated interplay of the involved movements generates counter-forces. It is similar to a car that instantly accelerates to its maximum speed and then immediately brakes to a full stop with absolute precision on a predetermined line.
de GRISOGONO’s unique sequential display module has more than 100 individual components. It has incorporated its own hand-wound or self-winding mainspring and barrel for providing the required reserve power. Another, more common mainspring-and-barrel unit provides the movement with a 44-hour power reserve.
Haute Horlogerie Design
de GRISOGONO OTTURATORE reveals a cambered rectangular case with a pair of large red gold push-pieces and a crown. All the construction components are crafted in 18K red gold. The crown is embellished with the de GRISOGONO crest.
The exclusive opaline dial of the timepiece has been designed specifically to correspond to de GRISOGONO's innovative approach to time displays. The design of the dial is characterized by contrasts and plurality of levels. The dial is built in two parts - lower plate, upper mobile sequence selector and upper plate.
The dial demonstrates a cobbled 'Clou de Paris' pattern created in de GRISOGONO grand tradition. It is completed with the ideally proportioned 'dauphine' style hour and minute hands in 18K red gold matching the strict geometry of the case.
The OTTURATORE's 'hidden face' is protected by a cambered sapphire crystal. The transparent case back allows to admire the heart of the watch. The timepiece, 30-meter water-resistant, is coupled with a Croco leather strap fitted with a double-deployment clasp in 18K red gold.
