Piaget is the undisputed master of ultra-thin. The brand holds several world records for thinnest movements, both simple and complicated. At SIHH, the list of records grew by two with the introduction of the Piaget Altiplano Skeleton Ultra-Thin. Learn more about the new records, and find wallpaper and pricing information inside.
Designing and constructing ultra-thin movements is part art and part science. The science and engineering side requires deep understanding of materials and movement architecture. The movement designers and engineers must not sacrifice rigidity to achieve a thin profile.
Yet even the best theories provide only a starting point. In the real world, nothing beats experience, and Piaget is among the most experienced manufacturers in the ultra-thin realm. In 2010 the brand celebrated the 50th anniversary of the groundbreaking caliber 12P. Piaget currently offers 18 thin calibers, ranging from simple manual-wind two-hand models to automatic tourbillons and perpetual calendars.
Piaget also has years of experience creating openworked or skeletonized movements, and here too the Altiplano Skeleton Ultra-Thin pushes the boundaries. It is the world’s thinnest self-winding skeleton model (5.34 mm), housing the world’s thinnest self-winding skeleton movement (2.40 mm).
Creating the Calibre 1200S required more than three years of research and development. To ensure optimum rigidity and pleasing aesthetics, the design incorporates long curves extending across the mainplate and bridges. The micro-rotor is in 950 platinum. The balance-bridge features a new aesthetic. The hour-wheel bridge has been slimmed down to a minimum wall thickness of just 0.11 mm.
Beyond the shapes and sizes, the finishing is both striking and very finely executed. The stylistic effect is based on the alternation between matte surfaces – sunray brushed or sandblasted – creating a contrast with the polished angles and the varied rhodiumed or black colors.
The in-house design and execution does not stop with the movement. Piaget is one of the few companies that also produces its own cases. The Piaget Calibre 1200S is housed within a 38 mm-diameter white gold case specifically designed and developed to accommodate it.
The Piaget Altiplano Automatic Skeleton retails for $60,000.
