The Thinnest Watch is Here

Coming in at 2 mm thick, the Piaget Altiplano Ultimate Concept is the worlds thinnest mechanical watch.

The incredible technical feat of conceptualizing and producing the world thinnest mechanical watch is awe inspiring. The watch’s concept was unveiled in 2018 and it wasn’t until 2020 when this watch was fully released in its beautiful physical form.

All of the components of the watch were thinned out to make it fit in the tolerances of this absolutely minute case. It features an ultra thin crystal, integrated winding crown, a case that forms part of the movement, different construction for the barrel and energy regulations.

Boasting an impressive power reserve of around 40 hours it will last a whole day before needing to be wound. This incredible technological innovation has yet to be surpassed.

Piaget: A brief history

Piaget started in 1874 in the Swiss Jura mountains nestled in the small village of La Côte-aux-Fées. The founder Georges-Édouard Piaget set up his first workshop in 1874 at the age of 19.

Timothee Piaget, the founders son, took over the company and morphed it from creating primarily movements to a manufacturer of luxury wristwatches and pocket watches. In 1943 Piaget became a registered trademark. The acceleration to what we see today with this company comes from the third generation of the family, Gerald and Valentin Piaget.

Valentin Piaget started the craze with ultra thin wristwatches. This was pursued to make it one of the signatures of the brand. With 1957 turning the corner, the hand-wound 9P caliber took Piaget to the forefront of ultra thin movements. In 1960, the micro-rotor concept allowed the company to create the thinnest movement in the world. The 12P Caliber.


What a mesmerizing piece. A brilliant display of ingenuity to reach a desired goal. Inspirational in the regards of how innovation and dedication can lead to such an outstanding result. The watch is sleek with just the right dash of complexity in the dial. The visibility of the components and movement drive the appeal of this watch in my opinion.

It would be lacking if the watch hid these component behind a dial. It is likely that the components are displayed in such a way out of necessity to make the components fit.

The strap seems to warrant frequent use. It is a watch that is technically incredible and wants you to wear it all the time. It would be hard to resist. The profile alone of this watch makes it hard to believe that it is indeed a real and functional mechanical watch.

Who knows if this watch will ever be surpassed.
