The Worlds Thinnest Automatic Wristwatch Piaget Altiplano
The pre-SIHH releases continue with the latest from Piaget – the Altiplano Ultimate Automatic 910P.
This watch become now the world’s thinnest automatic watch to date, at 4.30mm overall.
This trumps the Bulgari Octo Finissimo Ultra-Thin Automatique, which measures 5.15mm.
Piaget is no stranger to manufacturing super-thin wristwatches.
The caliber 9P, in 1957, presented itself 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.
The Piaget Altiplano Ultimate is now the thinnest automatic watch, measuring 4.30mm thick.
The Altiplano Ultimate Automatic is available in pink and white gold and features an ultra-thin automatic movement: the caliber 910P.
The secret to the slim dimensions is the same as in the hand-wound 900P, on which the 910P is based.
The case also functions as the baseplate of the movement, so there’s actually no conventional, separate movement and case.
It’s worth noting that though the 910P is now the thinnest automatic watch in production in absolute terms.
Thus, Bulgari Octo Finissimo remains the thinnest self-winding watch in the world with a conventional movement and case construction.
This is a design solution for ultra-thin watches originally pioneered by Audemars Piguet, for the automatic tourbillon caliber 2870, all the way back in 1986 (which is 4.8mm thick).
The automatic winding system uses a peripheral rotor, which allows it to lie in the same plane as the rest of the gear train.
The peripheral rotor means the 910P is slightly wider than the 900P: 41mm vs. 38mm respectively.
There are a total of 238 components, with some of the wheels measuring just .12mm thick.
Overall this watch has a power reserve of 50 hours, and the time display is featured on the eccentrically placed dial.
We will be able to get an in-person look at SIHH so stay tuned for more hands-on images in January 2018.
The price for the white gold version can reach $27,000 and for the pink gold version $26,000.
