Piaget ref. 9804 bracelet watch

Partially verified

This Piaget reference 9804 is an 18ct white gold wristwatch, manufactured in 1970. The timepiece is characterized by its oval case measuring 24 x 27mm and an integrated bracelet measuring approximately 142mm in length. The dial is composed of lapis lazuli and features white gold dauphine hands. The bezel is set with diamonds and includes sapphire quarter markers. The watch is powered by the manual-wind Piaget Calibre 9P, which was introduced in 1957. The construction of this movement, measuring only 2mm in thickness, allowed for the slim design of the watch case. This piece reflects the use of stone dials and integrated bracelets, which became identifying features of Piaget designs following the introduction of the 21st Century collection in 1969.

Object description

Case and Bracelet Construction

The watch features an oval-shaped case measuring 24 x 27mm, crafted from 18ct white gold. The bezel surrounding the lapis lazuli dial is set with diamonds and features four sapphire markers positioned at the quarters. The watch is completed by an integrated bracelet, also fashioned from 18ct white gold, which features a textured finish across its surface.

The overall design is representative of the integrated bracelet style associated with Piaget from the late 1960s. The bracelet length is approximately 142mm, designed to integrate seamlessly with the shape of the oval case.

Evidence for this section
  • “18ct white gold and lapis lazuli”
  • “Lapis lazuli dial with diamond set bezel featuring sapphire quarter markers and white gold dauphine hands”
  • “18ct white gold intergrated bracelet length approximately 142mm”

Movement and Dial Details

The watch is equipped with the manual-wind Calibre 9P. First released in 1957, this movement is recognized for its ultra-thin profile of 2mm. The minimal thickness of the Calibre 9P allowed for the production of watches with reduced profiles, enabling the focus to remain on the aesthetic design of the watch exterior.

The dial is made from a thin piece of lapis lazuli. It includes white gold dauphine hands and features the 'Piaget' name at the top with 'SWISS' printed at the bottom edge.

Evidence for this section
  • “Calibre: 9P”
  • “Released in 1957, the 9P was only 2mm thick”
  • “These stone dials became a signature of Piaget and were of unparalleled beauty and quality.”

Historical Context

Piaget utilized the Calibre 9P as a foundation for various designs within its 21st Century collection, which was introduced in 1969. This collection emphasized the use of integrated bracelets and watches that featured precious metals and stone dials.

This specific reference, 9804, was produced in 1970, shortly following the launch of the 21st Century line. The design of this piece aligns with the move toward integrated bracelets and the incorporation of natural stone materials as a primary visual element.

Evidence for this section
  • “the 21st Century collection from 1969 which included a host of integrated bracelet watches”
  • “Made: 1970”

Open research questions

  • What is the specific movement serial number associated with this case?
  • Was the lapis lazuli dial provided as a standard configuration for reference 9804 in 1970?
