Is your Altiplano
the real deal?
The Piaget Altiplano is one of the thinnest watches in the world, a masterpiece of ultra-thin watchmaking in precious metals. Its prestige and high prices make it a target for counterfeiters who cannot replicate the ultra-thin movement technology.
How to authenticate a Altiplano
Ultra-Thin Case
The Altiplano is defined by its impossibly thin profile — some models are under 5mm thick. The case should sit incredibly close to the wrist with a barely-there feeling. Counterfeits cannot replicate the ultra-thin movements and are always noticeably thicker.
Precious Metal Weight
Altiplano watches come in 18k gold, white gold, or rose gold. Despite being thin, the watch should feel appropriately heavy for precious metal. The gold should have a warm, rich tone. Counterfeits use gold-plated base metals that feel lighter and have a yellowish tint.
Ultra-Thin Movement
Piaget's ultra-thin calibers (like the 1200P at 2.35mm thick or the 900P at just 3.65mm) are visible through the case back. The movement should display exceptional finishing despite its thinness. Counterfeits use standard-thickness movements.
Dial Finishing
Altiplano dials range from classic silver sunburst to exotic hard stone materials. The surface should be perfectly finished without any imperfections. The applied indices and hands should be proportionally thin to match the ultra-thin aesthetic. Counterfeits have thick hands and poor dial quality.
Slim Hands
The Altiplano uses extremely thin, elegant hands that complement the ultra-thin design. They should be perfectly straight and evenly finished. Counterfeits use standard-weight hands that look disproportionately thick on the thin dial.
Alligator Strap
Genuine Altiplano straps are ultra-slim premium alligator leather with a signed 18k gold pin buckle or deployant clasp. The strap should be thin to match the watch profile. Counterfeits use thick, stiff leather with plated buckles.
Altiplano counterfeit warning signs
Noticeably Thick Profile
The Altiplano's defining characteristic is its extreme thinness. If the watch appears to have normal thickness or sits high on the wrist, it cannot house a genuine Piaget ultra-thin movement and is counterfeit.
Light Weight
Even though thin, 18k gold has significant density. If the watch feels lightweight or hollow, the case is gold-plated base metal and the watch is counterfeit.
Thick Hands and Indices
Everything about the Altiplano should convey thinness and elegance. If the hands, indices, or any elements appear thick or heavy relative to the case, the watch is a counterfeit that used standard components.
Standard Movement Visible
If the movement through the case back appears to be a standard-thickness caliber rather than Piaget's distinctive ultra-thin architecture, the watch is fake.

Frequently asked questions
How thin is the Piaget Altiplano?
The thinnest Altiplano models are remarkable feats of engineering. The Altiplano Ultimate Concept is just 2mm thick total. The standard Altiplano with manual wind is about 5.25mm, while the automatic version is approximately 6.36mm. These dimensions are achieved through Piaget's proprietary ultra-thin movements, some of which are under 2.5mm thick.
Is the Altiplano fragile?
While the ultra-thin construction requires more careful handling than a robust sports watch, the Altiplano is designed for daily wear. It is water resistant to 30 meters. The sapphire crystal protects the dial, and the precious metal case is durable. However, it is a dress watch and should not be subjected to sports or heavy impacts.
What makes ultra-thin watchmaking difficult?
Creating ultra-thin movements requires extreme precision — tolerances are measured in hundredths of a millimeter. Components must be miniaturized while maintaining reliability. The mainspring must be thin yet provide adequate power reserve. Assembly requires exceptional skill as thin components are fragile. This is why only a few brands like Piaget can produce truly ultra-thin watches.
