The Altiplano G0A29120, seen from the bench

The Altiplano represents Piaget's ultra-flat collection, characterized by minimized thickness. It is equipped with the manual-winding caliber 430P with hour and minute indication. The movement, with a thickness of only 2.1mm, is positioned among the thinnest in the world in its category.

Frequently asked questions

What is the exact lug width of the Piaget Altiplano G0A29120?

The lug width of the Piaget Altiplano G0A29120 is 18 mm. This measurement, taken from the internal shoulder of one lug to the other, is the classical standard for timepieces of this proportion and ensures access to an extensive selection of compatible artisanal straps.

What is the best strap for the Piaget Altiplano G0A29120?

The optimal strap for the G0A29120 depends on intended use and aesthetic preference. For maximum formality, an alligator in medium brown with vegetable tanning enhances the austere character of the yellow gold case. For contemporary versatility, a NATO in navy blue or taupe grey introduces functionality without compromising elegance. For those desiring visible temporal evolution, a vegetable-tanned calf strap develops unique patina over time, synchronising with the gold.

How do I change the strap on the Piaget Altiplano G0A29120?

Strap replacement is a straightforward procedure. Obtain a spring bar tool with dual-tip design. Position the watch on a flat surface, access the rear of the lug, insert the fine tip of the tool beneath the elastic pin until a release click is felt, remove the old strap, insert the new one by aligning the elastic pin with the aperture. Repeat for the opposite lug.

Is an aftermarket strap compatible with the G0A29120?

Yes, any strap with an 18 mm lug width is compatible. The artisanal straps from Milano Straps, crafted in structured leather, alligator, shell cordovan or NATO, adapt perfectly to the lugs of the G0A29120. It is essential to verify that the width is precisely 18 mm and that the strap thickness does not exceed 2.5 mm at the passage point.

How long does a leather strap last on the Piaget Altiplano G0A29120?

The lifespan of a leather strap depends on material quality, tanning method and frequency of use. A quality alligator or calf strap, if properly maintained (dry, away from prolonged moisture and heat sources), can endure 3-5 years of daily wear. A NATO strap in technical canvas has potentially unlimited longevity. The patina that develops over time is not degradation but aesthetic enrichment of the leather.
