With a portfolio comprising 35 calibres of which 23 are regarded as ultra-thin and 12 have set records, Piaget has for decades been liberally cultivating the art of slenderness. As a prelude to its 140th anniversary, the House renowned for its powerful and elegant watch and jewellery creations sets a new world record while displaying a wealth of imagination : measuring a total 3.65 mm thin, the Altiplano 38mm 900P becomes quite simply the thinnest mechanical watch ever. Whether a fortunate numerical coincidence or a token of destiny, the Altiplano plateau after which is it named is located on the Andes Cordillera at an altitude of 3,650 metres! It took the engineers, designers and watchmakers at Piaget – which produces all its cases and movements in-house a full three years to develop this model. Not only did they have to reduce the size of the parts (such as the wheels now measuring a mere 0.12mm), but also to entirely redesign the case so that its gold back would actually take the place of the movement mainplate – and then incorporate the dial and hands into the thickness of the bridges by a patented system. This new perfectly harmonious technical and aesthetic approach detracts nothing from the inimitable Altiplano spirit. Its understated and prestigious identity pervades all four versions of the model, while its chamfered and satin-brushed finishes are admirably highlighted by the miniaturisation of the material.
