Piaget Introduces the World’s Thinnest Automatic Watch

In 1957, Piaget launched its famous 9P caliber, which measured 2 mm in depth, distinguishing itself in the field of ultra-thin watchmaking. The groundbreaking movement was the catalyst in the creation of the Piaget Antiplano ultra-thin watch line – a tradition that continues to this day. In 2017 the brand celebrated its 60th anniversary of the Antiplano line.

In 2014 Piaget launched the 900P Antiplano, using a groundbreaking design and construction process that merged the movement with the case. This produced the world’s thinnest mechanical watch with a depth of only 3.65 mm. A year later it introduced the Altiplano Chronograph, the world’s thinnest chronograph.

For SIHH 2018, Piaget has announced the Altiplano Ultimate 910P. At 4.30 mm in depth, it is the world’s thinnest automatic watch. It boasts the same design and construction concepts as the Altiplano 900P mechanical watch. It is the result of a combination of technologies and know-how of both of the brand’s two manufacturing facilities: La Côte-aux-Fées where the movements are developed; and Plan-les-Ouates, where watch exteriors are designed and crafted. The whole process took three years to complete.

Everything in this watch is designed to take up as little space as possible. The caseback serves as the baseplate for the movement components, which eliminates one layer of thickness. The small hours and minutes dial is offset at 10 o’clock and integrated within the thickness of the caliber. The 219 movement components are merged within the case. All of the movement components are no thicker than the balance wheel. All of the bridges are fitted on the dial side in what the brand describes as “reversed movement construction.”

The 910P has a sapphire glass especially engineered to resist bending against the hour and minutes hands if pressure is applied. As an added precaution, the hands are located below the bridges, freeing up space between the cannon-pinion and the glass.

Stylish and elegant, the Altiplano Ultimate 910P is available in two models: 18k white gold for $27,000; and 18k rose gold for $26,000.
