Just when we didn't think it was possible to best the Bulgari Octo Finissimo Ultra-Thin Automatique, which measures 5.15mm, Piaget has once again wrested the title of "World's Thinnest Automatic" watch back again.

In the horological world where records tend to be beaten by mere tenths of a millimetre, Piaget's newest creation beats its predecessor by a whopping 0.85mm.

Bulgari had previously broken the record set by Piaget with its 5.25mm-thick Altiplano.

As a testament to its proud legacy in the field of ultra-thin watchmaking, helped in no small part by the combined excellence of its two integrated Manufactures, Piaget proudly presents the Piaget Altiplano Ultimate Automatic 910P.

Piaget is no stranger to manufacturing super-thin wristwatches. The caliber 9P,  in 1957, was at the time the thinnest movement ever made, at just 2mm thick, and the automatic caliber 12P, introduced in 1960, was only 2.3mm thick.

Three years after the launch of its revolutionary slimmest manual-winding watch in the world at that time, the Altiplano Ultimate Automatic at 4.30mm represents the nearly-the epitome of the Swiss manufacture's constant quest for infinite slenderness. This, along with the elegance and refinement prized by Piaget.

2017 marked the 60th anniversary of its Altiplano line and of its ultra-thin 9P movement, and this year the Altiplano Ultimate Automatic takes this a step further, becoming a record-holder for its extreme thinness, and the ultimate symbol of elegance.

Classic and modern, exclusive and elegant, the timeless Altiplano embodies the essence of luxury and the purity of innate style.

Available in white gold for US$27,000 and pink gold for US$26,000.
