Object description

Case and Dial Construction

The timepiece features an 18k yellow gold case measuring 25mm in width by 22.5mm in length. Centered within this is a distinctive, vivid blue lapis lazuli dial, which is further framed by an additional diamond-set surround.

The integrated articulated bracelet is constructed of yellow gold and enhanced with rows of brilliant-cut diamonds. The dial itself provides a minimalist display, featuring two-handed timekeeping without indices, allowing the lapis lazuli stone to remain the primary visual element of the face. The case and dial are signed by the manufacturer.

Evidence for this section
  • “The watch is defined by its ornate, gem-set aesthetic, specifically an elaborate bezel showcasing graduated baguette-cut diamonds. Centered within this is a distinctive, vivid blue lapis lazuli dial, which is further framed by an additional diamond-set surround.”

Movement and Mechanics

The watch is powered by a manual-winding, 18-jewel caliber 16-250 movement. This caliber serves as the technical engine for the decorative external components. The movement is signed by Patek Philippe, corresponding with the signatures on the case and dial.

This movement utilizes 18 jewels to reduce friction within the gear train. The manual-winding mechanism requires the user to interact with the crown to store energy in the mainspring, consistent with the functional requirements of luxury manual watches of this era.
