Introducing: Piaget Goes All In On Stone Dials, Led By The New Polo 79

No brand leans into stone dials quite like Piaget. For 2026, the Maison expands its use of ornamental stones across a wide-ranging lineup, led by a new Polo 79 with a deep blue sodalite dial. Piaget’s relationship with hardstone goes back to the early 1960s, when it began experimenting with materials like lapis lazuli, turquoise, malachite, and tiger’s eye, turning the dial into the focal point of the watch. At the time, stone dials were one of the only ways to achieve saturated, uniform color on a watch, giving Piaget a distinctly different visual language from its peers. By the 1970s, that approach had become a defining part of the brand’s identity, aided by the ultra-thin 9P movement, which allowed for wider, design-forward dials.
