Calling upon its avant-garde mind-set and daring expertise, de GRISOGONO has created a wristwatch equipped with a flying tourbillon featuring an inclined balance-staff. Acknowledged for its talent in the field of engineering and construction, de GRISOGONO presents a daring evolution of a technology developed by watchmakers of the past, such as Richard Daners.
Given that the position of a wristwatch frequently shifts between vertical and horizontal planes, the effect of the tourbillon is less pronounced, since the plat-pendu phenomenon lead to a loss in timekeeping performance in watches equipped with this device. To alleviate the problem of gravity’s influence on a wristwatch escapement independently of its direction, de GRISOGONO has gone beyond the traditional tourbillon to create a flying tourbillon fitted with a balance-staff inclined at a 30° angle.
The choice of the 30° slant was determined by both technical and aesthetic reasons. This optimal Inclination brings notable improvements and perfectly compensates for the variations in rate stemming from the plat-pendu phenomenon. The INSTRUMENTO N° UNO TOURBILLON is a time-measuring instrument ensuring stable rate in all positions.
The original design of the INSTRUMENTO N° UNO has been technically and aesthetically modified. de GRISOGONO has developed a totally innovative case with redesigned proportions reaching a generous volume of 59.2 mm x 33 mm x 14.99 mm, composed of a hybrid sapphire and precious metal structure and fitted with an original aperture at 6 o’clock revealing the off centred tourbillon.
A wealth of well-mastered details is on display beneath an elegant and daring three-dimensional sapphire lens. The architecture of the watch plays on transparency and allows the flying tourbillon with inclined balance-staff to work its visual magic. The INSTRUMENTO N° UNO TOURBILLON houses a rectangular-shaped movement in which the mechanical components and their aesthetic signatures are fully revealed through the see-through case. In a nod to the brand’s jewellery background, the spoke of the skeleton-worked oscillating weight is adorned with a diamond-shaped opening.
As far as the movement’s technical characteristics are concerned, it is equipped with a twin barrel and has a three-day (72-hour) power reserve. Its mainplate and bridges are skeleton-worked, graced with polished angles and clothed with a matt black PVD coating. Its 266 parts are accommodated within a total volume measuring 9.29 mm thick, 26.8 mm wide and 34 mm long. The tourbillon itself is composed of 62 parts weighing just 3.6 grams.
