We really like some of Piaget’s watches here at WristReview; they always bring their own quirky elements to their pieces, and they usually come with the horological chops to match. Although the Polo S collection has, in recent years, garnered the most attention due to the wide range of pieces in that collection, the Altiplano should still be considered as Piaget’s ‘halo’ model. The one most of us aspire to when we look at their watches. For late 2025, Piaget introduces two new watches in the Altiplano collection for us to fawn over, well, for me to fawn over. Let’s take a look.
Piaget Altiplano Ultimate Concept Tourbillon G0A50530
Piaget’s Ultimate Concept Tourbillon was introduced in 2024 at Watches & Wonders and was billed as the world’s thinnest tourbillon watch, a staggering 2mm thick. But, if you’ve been following the recent battle for ultra-thin supremacy, you’ll know that the rate at which the world’s thinnest (insert complication here) watch changes is greater than the rate at which I go on a tangent when writing. And that’s pretty often. The thinnest tourbillon watch is currently Bulgari’s Octo Finissimo Ultra Tourbillon, which is 1.85mm, 0.15mm thinner than the Altiplano.
Don’t let that distract you from the Piaget, though, because what this watch has in spades is class. The khaki green of the calfskin/kevlar strap matches the coloured sections of the dial. The time is displayed in the top right corner, along with a plaque reading “1874,” the year Piaget was founded. Below that at 6 O’clock is the open mainspring barrel, and the ultra-thin flying tourbillon cage can be found above that in the top left corner.
As has been the case for most of the Altiplano watches since 2014’s Altiplano 900-P (or possibly earlier), the case also makes up the baseplate for the movement, allowing the watch to be as thin as it is. The 41.5mm x 2.00mm case is made of a cobalt alloy and, amazingly, is water resistant to 20m. The calibre 970P-UC is wound and set by the crown which is hidden within the case edge at the traditional 3 O’clock position. The movement runs at 4Hz for a minimum of 35 hours.
The price of one of these is around €730,000.
Piaget Altiplano 910P Khaki Green G0A50126
It’s crazy how times have changed, isn’t it. The Altiplano 910P was once one of the world’s thinnest mechanical watches, but measuring 41mm x 4.3mm in 2025 means it looks positively fat. Still, a case measuring 4.3mm thick (including the crystal) is significantly thinner than most mechanical watches, and the fact that Piaget continues to produce the 910P indicates that there is still demand for it.
This new watch comes with an 18k yellow gold case with 20m of water resistance. Attached to it is a khaki green alligator leather strap with an 18k yellow gold buckle.
The watch’s khaki green dial, like on the Altiplano Ultimate Concept, is also a part of the calibre 910P, with the escapement and various wheels being on display on the front. There’s also a winding rotor in there , as the 910P is an automatic watch, meaning that the 50-hour power reserve can go on much longer as long as you wear the piece.
The price for this model is approximately €40,500.
So, which of these two is your favourite? Did Piaget utilise green, the colour of the moment, well in these watches? Let us know your thoughts in the comments!
