Presenting the Piaget Altiplano 38mm 900P
For over half a century, Piaget reigns within the ultra-thin world. The 9P, introduced in 1957, continues to be a reference within the the watchmaking industry niche for being one of the first ultra-thin caliber ever. Out of this date, many rivals attempted to achieve exactly the same degree of expertise: Jaeger-LeCoultre, Vacheron Constantin, among others. Actually, there is just one manufacture in a position to break Piaget’s record: Piaget itself. Please welcome the Piaget Altiplano 38mm 900P, the world’s slimest mechanical watch. Merging the hand-wound calibre using the case elements, it's designed like a single entity to be able to achieve record-breaking slenderness just 3.65 mm thin.
Very few producers develop and convey in-house both their calibres and their cases. Piaget goes for this circle. As the Piaget Altiplano 38mm 900P merges the case and movement to determine itself because the slimest mechanical watch ever, additionally, it comes from another fusion without which this type of task could have been impossible: that of these two Manufactures Piaget – one located in La Cote aux Fees, in which the movements are created and yet another in Plan-l'ensemble des-Ouates, in which the cases are crafted. These abilities are actually intermingled, since inside the Altiplano 38 mm 900P, the mechanism and also the exterior components form just one indivisible entity.
For any full 3 years, watchmakers, case constructors and designers labored together each and every stage of development, production, adjustment and finishing to be able to give existence into it. Each technical choice had a pleasing impact, and the other way around. While each one of the 145 parts creating the Piaget Altiplano 38mm 900P continues to be trimmed to some size sometimes barely thicker than the usual hair’s breadth. Objective for Piaget : create optimal play between your fixed and mobile organs, while fostering to make sure that the later move freely and therefore ensure the smooth running from the mechanism.
The key from the 900P is based on the dwelling from the case itself, which the rear also can serve as the mainplate. Therefore merging calibre and case, the second was machined from the case-back to be able to house the mechanical parts. This complex architecture meant curing movement construction in order to fit the bridges around the dial side.
Finally, Piaget has devised a suspended barrel hanging from one bridge around the dial side, unlike classic barrels which are also fixed towards the mainplate side. This unusual system is not a way harmful towards the performance from the mechanism, because the Piaget Altiplano 38mm 900P includes a generous power reserve close to 48 hrs.
Whenever a watch is exposed to strong pressure, for example when submerged in water, its glass or crystal is slightly deformed. Although this physical phenomenon goes relatively undetected on the classic watch, exactly the same is not the case with an ultra-thin watch. Because of the very limited available space, the glass could be prone to press around the hands when deformed, thus leading to the movement to prevent. To avert this challenge to the ultra-thin model, Piaget has develop a tool (patent pending). Rather than fitting the hands over the bridges, Piaget has placed them underneath, therefore clearing up space between your cannon-pinion and also the crystal. Once the latter is deformed through the results of pressure, it presses this is not on the hands - placed underneath the bridge level - but rather around the wheel-train bridge, thus staying away from any effects around the rate from the movement.
