Not quite a movement, not quite a case, but rather both at once - the Altiplano 38 mm watch is a unique concept, and resolutely proud of its status as one of the thinnest and most elegant mechanical timepieces in the world. The model was designed to merge hand-wound caliber and watch exterior into a single concept, and is only 3.65 mm thick. The pinnacle of a half-century of virtuosity in the field of ultra-thin watches, in which Piaget reigns supreme, this luxury watch testifies to the sheer excellence of the Maison's two integrated Manufactures – where watchmakers, case makers and designers joined forces to bring to life this masterpiece of reliability and precision. The secret of this extreme thinness lies in fact in the very concept of the case, the back of which also serves as the bottom plate. Merging the caliber with the case, the bottom plate has been machine-tooled to accommodate the mechanical components. This most complex of structures has also necessitated the reverse construction of the movement, with bridges fitted on the dial side, thus rendering them visible and so contributing to the watch’s aesthetic appeal. Forming an elegant contrast to the rose gold of the case, the beveled and satin-finished “sunburst”-motif bridges have a black surface treatment. To gain vital millimeters, the whole mechanism and hand system is contained within the thickness of the balance, with an off-center hours and minutes display as a consequence of this, perfectly attuned to the emblematic style codes of the Piaget Altiplano collection. These codes are further enhanced by the visible gear train, inviting wearers of this luxury watch to delve into the heart of an extremely elegant and sophisticated mechanism. Adapting to the extremely reduced space available, Piaget designed a suspended barrel, held in place by a single bridge on the dial side, unlike conventional barrels, which are also attached on the bottom plate side. However, this unusual system does nothing to hamper the mechanism's capacity, as the ultra-thin Piaget Altiplano 38 mm model boasts a generous power reserve of around 48 hours!
