As the world continues its obsession with thin, air-like electronics, Piaget joins in on the design theme with a watch that takes prize of being the world’s thinnest mechanical. Measuring in at a razor thin 3.65mm, the Altiplano 38mm 900P watch snags the title from Jaeger-LeCoultre by a full .4mm. So, how did they pull it off? Well, the answer is literally right in front of you: the watch designers built the movement – all the gears and mechanisms that power the hands – directly into the watch’s body and utilized the available space to position the hands. So, not only is the watch thin, comfortable, and interesting to look at, it’s also a bit of technological marvel, produced with extreme levels of precision. Unfortunately, the price tag isn’t equally thin, coming in at a fat expected price of between $20,000-$30,000 when it launches in the coming weeks.
