Piaget Altiplano 9025 Diamond 18k 1990s

A testament to Piaget’s mastery in ultra-thin watchmaking, the Piaget Reference 9025 is a timeless piece of horological art. Crafted in the early 1990s, this vintage dress watch exudes understated sophistication with its minimalist design and flawless execution.

Encased in 18k white gold, the case measures a sleek 33mm in diameter and houses a manual-wind 9P movement, celebrated for its remarkable thinness—just 2mm thick—one of the slimmest mechanical movements ever produced. This engineering feat allows the watch to maintain a refined and svelte profile on the wrist, perfect for formal occasions or elegant daily wear.

The dial is a study in simplicity: a clean, dark grey sunburst finish—accentuated by twelve diamond hour markers and delicate dauphine hands. The absence of a seconds hand or date complication enhances its pure aesthetic, allowing the wearer to appreciate the essence of time itself.
