Piaget Altiplano Ultimate Concept Unique Piece, Reference G0A47505

After creating the unique green dial La Côte-Aux-Fées edition of the Altiplano Ultimate Concept in 2021, Piaget now presents a new one-of-a-kind watch featuring a sparkling midnight blue background evoking the star-studded sky above La Côte-aux-Fées.

A record-breaking timepiece in the ultra-thin segment, the Altiplano Ultimate Concept was first presented in Geneva at the Watches & Wonders fair in 2018. In April 2020 the first timepiece left the Piaget workshops, and in November of the same year, it won the prestigious Aiguille d’Or prize from the Grand Prix d’Horlogerie de Genève.

With a thickness of just 2mm, the Altiplano Ultimate Concept was the thinnest mechanical hand-wound watch when it was unveiled in 2017. Presently, Bulgari Octo Finissimo Ultra (released in 2022) holds the world record in this category with a 1.80mm thickness.

Most timepieces are made up of four layers: 1) the bezel and crystal, 2) the dial and hands, 3) the movement, and 4) the case back. Piaget removed this four-layer construction to create a fusion of components with the bridges, dial, and hands, on one side, and the case back, movement, main plate and bezel on the other, all coming together as one.

This fusion of watchmaking construction features five patents that have enabled the Maison to create a timepiece that is a mere 2mm in height, from the underside of the caseback to the top of the sapphire crystal.

Starting at the top of the dial, the Piaget logo is in a historic font that is the same typeface used in the logo above the manufacture in La Côte-aux-Fées, the village where Piaget was born and remains today.

Two enlarged circles sit among the dots of the minute ring, marking the time – 7:47 – when the AUC first came to life. At 2:30, the birthday of the AUC – 7th February 2017, is inscribed in a small window. And a “La Côte-aux-Fées” inscription has also been engraved onto the ratchet wheel along with the manufacture’s GPS coordinates.

Completing the tribute, the background of the dial features stars illuminated with Super-LumiNova that replicate the sky above La Côte-aux-Fées at the exact date and time of the AUC’s birth.

The caseback, bezel and lugs have all been satin brushed making a nice contrast to the case band that is polished. The timepiece is paired with an extremely thin dark blue alligator strap that does not exceed 1.5mm, in keeping with the watch’s ultra-thin design.

The Piaget Altiplano Ultimate Concept watch has a power reserve of 40 hours.
