This distinctive Piaget reference reflects the maison’s 1970s approach to watchmaking, where jewelry and timekeeping were closely intertwined. Crafted in 18K yellow gold, the rectangular case flows seamlessly into an articulated integrated bracelet, creating a fluid and sculptural silhouette. The dial is particularly striking, featuring vertically channelled gold surfaces with recessed areas that create a subtle interplay of light and shadow. The minimalist design is completed by a pair of simple faceted gold hands, while the vertical decoration continues onto the bracelet, creating a remarkable sense of continuity between the dial, case and bracelet. The dial is further distinguished by the unusual “Y. KOYABU” signature, probably referring to a Japanese jeweler or retailer, adding an intriguing and highly individual detail to the watch. Reference 4131 K51 is a refined example of Piaget’s 1970s aesthetic, combining precious materials, sculptural goldwork and geometric decoration in a distinctive wearable form.
