Piaget Diamond & Lapis Lazuli Dress Watch

In 1963, Piaget introduced ornamental-stone dials, beginning a remarkable period in which the Maison transformed traditional wristwatches into works of decorative art. Throughout the 1970s, its mastery of ultra-thin movements enabled increasingly expressive designs, combining precious metals, natural gemstones, and unconventional case architecture. Lapis lazuli, treasured since antiquity for its rich blue color, became one of Piaget's most distinctive materials.

Reference 9775 D23 captures the extravagance and refinement of this celebrated era. Crafted in 18-karat white gold, its sculptural cushion-shaped case surrounds a lapis lazuli dial accented by diamond hour markers, while a diamond-set bezel adds brilliance to the deep blue stone. An integrated white gold mesh bracelet completes the composition, transforming the watch into a seamless piece of fine jewelry. Beneath its decorative exterior lies Piaget's ultra-thin, manually wound caliber 9P2, reflecting the mechanical expertise that made such elegant proportions possible.

HISTORICAL & COLLECTIBLE SIGNIFICANCE

Piaget's ornamental-stone watches represent one of the most recognizable achievements of 1970s Swiss design, uniting traditional watchmaking with the artistic freedom of high jewelry. The combination of natural lapis lazuli, diamond setting, and finely worked gold distinguishes reference 9775 D23 from conventional dress watches of the period. Its significance lies in the craftsmanship required to bring these materials together and in its connection to the creative experimentation that defined Piaget before the introduction of the Polo collection in 1979.
