Piaget Altiplano Ultimate Automatic G0A45123, 18K White Gold, Full Set, 2022

An exceptionally thin and technically expressive contemporary Piaget, combining the maison’s long ultra-thin tradition with the architectural openness of the calibre 910P.

The Piaget Altiplano has long stood as one of watchmaking’s clearest expressions of elegance through restraint, and the Altiplano Ultimate Automatic G0A45123 brings that philosophy into a distinctly contemporary register. Crafted in rhodium-finish 18K white gold, this example measures 41 mm across while maintaining an extraordinary overall thickness of just 4.30 mm, placing it among the most technically accomplished ultra-thin automatic wristwatches of its generation. Piaget officially describes the model as one of the thinnest automatic watches in the world, with its caseback serving as the mainplate to which the movement components are affixed.

At the heart of the watch is the manufacture calibre 910P, an ultra-thin self-winding movement integrating case and calibre into a single architectural whole. Piaget lists the movement with 30 jewels, approximately 48 hours of power reserve, a frequency of 21,600 vibrations per hour, and technical features including the maison’s signature suspended barrel and the “P” fixed to the regulator assembly. The off-centred time display at 10 o’clock is framed by a blue lacquered chapter ring, while the rest of the dial reveals the movement structure from the front, giving the watch an unusual sense of depth and mechanical clarity despite its extreme thinness.

Specialist coverage has rightly emphasized that the appeal of the Altiplano Ultimate Automatic extends beyond record-chasing thinness alone. Writing about this white-gold blue-accented version, Monochromenoted that the model expresses Piaget’s decades-long mastery of ultra-thin construction through an inseparable case-and-movement design, open-worked dial architecture, and peripheral winding solution that preserves both slimness and visual balance. In collector terms, the reference is especially compelling because it unites technical innovation with a calm, highly wearable aesthetic rather than relying on spectacle alone.

The present example, serial number 1287913, is offered by its original owner and remains in excellent condition, showing only minimal wear. The visible movement architecture and dial remain pristine, while the case retains its original factory finish. The watch is fitted with a blue alligator leather strap and Piaget buckle, preserving the refined monochromatic character of the model.

Delivered as a full set, it is accompanied by its Piaget International Warranty card dated 25 March 2022, together with full documentation. Presented in complete, collector-friendly condition, this Altiplano Ultimate Automatic offers the opportunity to acquire one of Piaget’s most technically articulate contemporary wristwatches in a highly attractive and well-preserved configuration.
