According to the Archives of Piaget, the present necklace watch was manufactured in 1972.
The present watch is an impressive example of Piaget's exceptional 1970s watch designs. It is fitted with the ultra-slim 2 mm. calibre 9P movement, launched at the Basel Fair in 1957, its generous diameter offering new opportunities for visual expression. These watches were intended for a young and avant-garde clientele and were characterized by their asymmetrical shapes, large bracelets and the use of precious stones. The models confirm Piaget's creativity and originality earning it the coveted title of "the jeweller of watch making".
Propelled by the incredible creative momentum of the 1960s, Piaget raised hard stones to the rank of precious stones. The brand soon grasped the value of using these materials and immediately mastered the requisite production skills. Colour became the hallmark of the brand: jade, coral, lapis lazuli, tiger's eye, turquoise. Over 30 different stones were to adorn a stunning array of exceptional models, their interaction with light, inclusions and subtle nuances giving an unique character to each creation. Piaget created astonishing graphic effects by combining various hard stones. The latter indeed soon also invaded bracelets, transforming watches into full-fledge jewellery creations. A large selection of such exceptional pieces have recently been collected by Piaget in a sublime exhibition entitled L'Or et la Couleur. This exhibition was held in Geneva during the beginning of 2014 and was a great opportunity for the public to discover the fabulous heritage and savoir-faire of Piaget.
A very elegant example of such necklace watch is illustrated in Montres et Merveilles, 200 créations rares provenant du Musée de l'horlogerie de Genève et des Collections Privées Piaget, p. 73.
