While a mere glance is enough to confirm its membership of the Bovet by Pininfarina family, the Tourbillon OttantaSei is bursting with technical innovations and stylistic changes all harmoniously planned around a detailed series of specifications. The word “light,” with its dual connotations of luminosity and limited weight, was the watchword for every stage in the development of this project.
The case of the tourbillon watch fully embodies this “philosophy.” The technicians and watchmakers at the Manufacture Dimier 1738 together with the designers at Pininfarina pooled their expertise to come up with an unprecedented perspective on the originality and fascinating technology inherent to the movement, once again entirely developed and manufactured by Bovet.
Four large sapphire crystals occupy the main surfaces, while contrasting elements in titanium or gold trace the essential contours of the collection’s design and guarantee the qualities required for its sportier traits. Far more than just a case, it recalls a whole lexicon of aviation and evokes the glass surrounding the cockpit of an aircraft or helicopter. Without making the connection explicit, the Italian designers and technicians at Bovet 1822 took an active interest in the subject while developing the case, given that the constraints of rigidity, transparency and water-resistance are, relatively speaking, very similar.
To create maximum light and transparency, the upper and lower crystals have specific and complex forms. Two long side crystals enclose the case and embrace the profile of the middle perfectly. The accurate machining and delicate metallization of the sapphire crystals provide superb views of the movement, while the touch of elegance synonymous with both houses is present through the laser-engraved words ‘Pininfarina’ and ‘limited edition’ on the inner concave surfaces of these sapphire crystal walls. Of course, the distinctive screws designed by Pininfarina used on all the watches in the collection are also a feature. As regards the crown, although its winding surface is identical to all of the collection’s tourbillons, its top is set with a sapphire crystal laser-engraved with the emblematic Pininfarina logo above a polished mirror surface — an aesthetically stunning and ingenious way of showcasing the third dimension.
The case of the tourbillon OttantaSei also features a clever casing-up system via the caseback, ensuring greater transparency and lightness, as well as optimal dimensions for complete ergonomic comfort. With its 44mm diameter and a thickness of 8.85mm and 2 mm with and without the sapphire crystals respectively, the Tourbillon OttantaSei offers maximum comfort whatever the shape of the wearer’s wrist.
A quick glance at the movement is enough to conclude that here, once again, all efforts have been concentrated on the principles of lightness and transparency. Three distinct circles outline the movement’s organs and vital functions, with the balance and harmony that are so dear to Pascal Raffy. The eye alights first and foremost on the single barrel and its concentric power-reserve indicator at 10 o’clock. Then, it moves on to the hours and minutes displays featuring the same configuration at 2 o’clock, before finally considering the flying tourbillon in the airy space freed up at 6 o’clock.
So in order, we have: the driving organ (and its power-reserve indicator), the display, and finally the regulating organ. It is difficult to imagine anything clearer. To fully grasp both the density and absolute coherence of this new caliber, we must begin the chronological unveiling of its secrets with the exclusive winding system. The 10-day autonomy of the Tourbillon OttantaSei should involve twice as many turns of the crown than that required by the spherical differential developed and patented by the watchmakers at Dimier 1738. The extreme miniaturization of this mechanism has inspired them to file a second patent for the three-dimensional multiple meshing teeth, which drastically reduce clutter while optimizing the watch’s operation. This tourbillon watch can thus be wound twice as quickly to give it the power required for 10 days of autonomy.
