News: Pre-SIHH 2018 Piaget Altiplano Ultimate Automatic 910P. The World's Thinnest Automatic Watch with Peripheral Rotor.

Defying the limits of feasibility, Piaget provides a new demonstration of its supremacy in the field of ultra-thin watchmaking, stemming from the excellence of its two integrated Manufactures. Three years after the launch of the revolutionary slimmest manual-winding watch in the world at that time, Piaget is once again defying the laws of horology by presenting the new Altiplano Ultimate Automatic watch with a mere thickness of 4.30 mm. To celebrate the 60th anniversary of the Piaget Altiplano, Piaget has now added to their lineup what is now the world’s slimmest automatic watch.

Born in 1874 as a movement manufacturer in the village of La Côte-aux-Fées, and subsequently earning international renown as a brand in its own right, Piaget has constantly sought and found innovative solutions in the domain of slimness. Loyal to the family tradition of pursuing the ideal of perfection and perpetual daring, the founder’s grandson, Valentin Piaget, enabled the brand to distinguish itself both in the field of ultra-thin watchmaking and in creating a unique style imbued with timeless and assertive elegance. The pivotal step in this process was the launch of the manual-winding 9P calibre. One of the world’s thinnest movements of its kind at the time, measuring just 2 mm thick, was presented at the Basel Fair in 1957 and revolutionized the market. The 9P ensured enhanced legibility, but above all the opportunity to pursue a new ultra-thin watchmaking aesthetic by giving rise to an extremely pure design. At just 2.3 mm thick, the 12P calibre presented at the 1960s Basel Fair was another landmark event in watchmaking history: a true revolution hailed by the press and the profession as the world’s thinnest automatic watch. This degree of slimness, before thought to be unattainable, was made possible by the use of a 24-carat gold micro-rotor integrated within the movement so as to ensure efficient mainspring winding. At the time, the influential Journal de Genève daily newspaper wrote that the creation of the 12P represented “an event destined to be a milestone in the history of watchmaking” – a prediction that was to be fulfilled.

In 2014, the 140th anniversary of the Maison was celebrated by the launch of a revolutionary watch. The concept behind Calibre 900P, thus named in tribute to the legendary 9P movement, introduced an entirely novel construction that could only have been achieved by combining a range of numerous in-house skills possessed by Piaget.

Pursuing the year 2017 celebrations marking the 60th anniversary of its Altiplano line and of its ultra-thin 9P movement, Piaget unveils the Altiplano Ultimate Automatic, a distillation of technical excellence, a record-holder for its extreme thinness, and the ultimate symbol of elegance. In a world where records tend to be beaten by mere tenths of a millimeter, this watch lays a new milestone in the world of infinite thinness, at just 4.30 mm thick. The secret of this feat lies in its revolutionary construction.

Like the 900P concept movement, the Altiplano Ultimate Automatic breaks free of the distinction between movement and exterior elements, to set a new record: that of the world’s thinnest automatic watch. For three long years, the developers, engineers, watchmakers, designers, case and movement engineers, worked together on each stage of development, production and adjustment in giving life to this slender masterpiece – for which each technical choice has an aesthetic impact and vice versa. Designed as an inseparable whole to set a new thinness record, the movement and case form a single entity, with the latter serving as a mainplate to which the 219 incredibly thin components are affixed.

Pared down to extremes, some of the parts are barely thicker than a hair’s breadth, including certain wheels measuring just 0.12 mm thick —compared with 0.20 mm on a traditional movement. This highly complex architecture has led to a reversed movement construction, with the bridges fitted on the dial side —an approach that contributes to the inimitable aesthetic of the Altiplano Ultimate Automatic, since they are now visible through the front of the watch. This style vocabulary is further enriched by the going train which is also revealed, extending an irresistible invitation to the owner to let time stand still and revel in admiring this 41 mm diameter mechanical masterpiece available in 18K white gold and 18K rose gold.

To save these precious tenths of a millimeter, the entire mechanism and hand-fitting is contained within the thickness of the balance wheel, thus entailing an off-centered display of the hours and minutes that is entirely in tune with the emblematic design codes of the Altiplano line. Working within these extremely small confines, Piaget opted for a suspended barrel, held by a single bridge on the dial side, contrary to customary barrels that are also fixed on the mainplate side.

The Altiplano Ultimate Automatic enjoys a generous 50-hour power reserve. Driven by the same concern for optimizing use of the available space, the oscillating weight in 22K gold with black PVD coating is positioned on the movement periphery so as to be incorporated into its thickness and thus contribute to the overall slimness. The choice of gold for this technical component is essential as it allows a perfect machining, and it endows the oscillating weight with a weight, an inertia and a robustness guaranteeing excellent winding performance.

A patent has been filed for this major breakthrough aimed at enhancing reliability. When a watch is subjected to strong pressure, its glass is slightly distorted. While this physical phenomenon goes relatively unnoticed on a traditional timepiece, things are very different with an ultrathin watch. Given the fact that spaces are reduced to an absolute minimum, the glass would tend to press against the hands when thus distorted, causing the movement to stop. By fitting the hands below the bridges, Piaget thus frees up space between the cannon-pinion and the glass. If the latter is distorted due to pressure, it no longer pushes on the hands, but instead on the gear-train bridge and thus has no effect on the smooth running of the movement.

While Piaget is determined that the extreme slimming down of components in an ultra-thin watch must entail no sacrifices when it comes to reliability, the same holds true for the level of finishing. The Altiplano Ultimate Automatic is no exception to the rule. Machined in the actual watch case, the mainplate has been satin-brushed and sandblasted, while the wheels are alternately sunburst- or circular satin-finished. Hollowed out so as to afford an even better view of the subtle mechanism operating at the heart of the Altiplano Ultimate Automatic, the chamfered bridges are sunburst satin-brushed. The historical “Piaget Automatic” inscription that appeared on the very first ultra-thin timepiece from the Maison also sets the seal on this new watch, thereby paying tribute to the extremely rich history of the line. Finally, the index-assembly bearing the “P” for Piaget adds a final signature to this sophisticated Fine Watchmaking orchestration with chamfered and sunburst bridges, and black PVD coated screws set the final aesthetic touches to this exceptional watch. Reflecting the aesthetic codes lovingly cultivated by Piaget, all have been meticulously finished in keeping with the finest watchmaking traditions, while the delicate nature of this magnificent craftsmanship is further heightened by the extraordinary thinness of the elements involved.

An exceptional creation in many ways, whereby Piaget expresses its perfect technical mastery, along with its sense of understated and refined elegance, the Altiplano Ultimate Automatic flaunts its contemporary character while celebrating the 60th anniversary of ultra-thin watchmaking. It is the emblem of an authentic revolution in the history of the brand and of watchmaking itself. Never has an Altiplano so richly deserved its name.
