Object description

Case, Dial, and Bracelet

The watch features a square 18ct white gold case measuring 25mm. The bezel is decorated with an alternating pattern of diamonds and emeralds, providing a frame for the white gold dial. The dial layout includes simple baton-style hour markers and hands.

The case transitions into an integrated 18ct white gold woven bracelet. The bracelet assembly has a length of approximately 160mm. The overall design displays a uniform finish across the metal components, contrasting with the gemstone-set bezel.

  • “Diamond and Emerald set bezel”
  • “18ct white gold woven bracelet, length approixmately 160mm”

Movement and Technical Details

The timepiece is powered by the Piaget Calibre 9P. This mechanical movement was initially released in 1957 and is noted for its thickness of 2mm. The use of this thin calibre allowed for the slim profile of the watch case.

The movement is housed within the square white gold chassis. The reference 9203 A6 is clearly marked on the case back, confirming the model identification provided in the documentation.

Evidence for this section
  • “Calibre 9P”
  • “Released in 1957, the 9P was only 2mm thick and allowed Piaget to create watches where the size of the movement was negligible”
