What a champion Piaget! The Geneva-Neuchâtel manufacture has managed to create a timepiece that is even slimmer than an extra-slim, referred to as ultra-slim… To such an extent that it can declare urbi et orbi that its 38 mm Altiplano 900P model, that is only 3.65 mm thick, is nothing less than the “slimmest mechanical watch of all time”. A declaration, however, that is open to question. Specialists and bloggers picked up on the subject and began a relentless comparison of models, quibbling non-stop over the fact that there are a few more or a few less microns. Well, that’s what the world of watchmaking is sometimes like. As for us, we would prefer to try and answer the following question: is this variation of the Altiplano a technical and aesthetic success? The answer is yes. There’s no need for us to remind you of Piaget’s expertise in the field of everything extra-slim… expertise which is totally indisputable. The brand has been making calibres of this kind for over fifty years now. Among the 35 movements that it designed and developed in-house, 23 are extra-slim. It just goes to show! The 900P, equipped with 145 components, is as such perfectly in line with this.
