Pre-SIHH 2014: Piaget Altiplano 38mm 900P-World’s Thinnest Mechanical Wristwatch

By Jovan Krstevski




In 2014 Piaget will celebrate 140 years of history. To mark the occasion, Piaget has announced today the new Altiplano 38mm 900P, presenting it as the world’s thinnest mechanical watch with a thickness of just 3.65 mm. This new ultra-thin beauty pays homage to the brand’s historic ultra-thin 9P caliber from back in 1957. We have seen different ultra-thin creations from various brands in the past, but this is by far one of the most refined ultra-thin watches I’ve seen.


In order to make a watch this thin, the Piaget case design team and movement design team had to work together closely. The Piaget Altiplano 38mm 900P has a semi-skeletonized dial and shows parts of its ulta-thin movement. The balance wheel can be admired at an aperture at 7 o’clock on the dial. Black colored satin-brushed sunburst bridges, sunburst and circular brushed wheels, bevelled bridges, to black colored screws and a circular satin brushed caseback.

The movement is housed in a case in polished 18kt white gold with a diameter of 38 mm, features 20 jewels, oscillates at a frequency of 21,600 vibrations per hour and declares a power reserve of 48 hours. There are also 145 total components in this thin movement.



The Altiplano Piaget 900P is presented on a black alligator leather strap with white gold buckle .



The Ultra-Thin Altiplano 900P will be available in 18k white gold and will be priced between $20,000 and $30,000.
