In 1874, Georges Edouard Piaget established the Piaget Company in La Côte-aux-Fées, Switzerland, where he created precise mechanical complications for established watchmaking companies. As his skills became more known, the company became a family-run business. In 1943, the company was officially registered and became a brand, with watches designed and manufactured under their name. The company's grandsons, Gérald and Valentin Piaget helped make the brand more widely known.
In 1945, a new facility was built in La Côte-aux-Fées, leading to more complex mechanical movements. Piaget's watchmaking innovations included the Caliber 9P, a thin manual watch movement, and the Caliber 12P movement, the slimmest self-winding movement in the world at only 2.3 millimeters thick. This innovation opened up the doors for creating popular jewelry watches.
Piaget became known for their timepiece mechanics and as master jewelers, creating pieces such as jewel watches, coin watches, ring watches, brooch watches, cufflink watches, and matinee necklaces. In 1988, Piaget joined the Luxury Group, now known as Richemont, which owns several leading luxury brands. This allowed Piaget to grow and develop as a leading luxury brand.
