Gérald Genta Octagonal Pocket Watch

Partially verified

This Gérald Genta pocket watch is an octagonal timepiece housed in an 18K yellow gold case featuring a stepped bezel. Attributed to a production period around 1990, the watch integrates complex watchmaking features, specifically a manually wound movement equipped with a perpetual calendar mechanism and a minute repeater. The minute repeater functionality allows for the auditory indication of hours, quarters, and minutes. The silvered dial is marked by black Roman numerals and incorporates a moon-phase display composed of lapis lazuli. The watch measures 49mm in diameter. This entry catalogues the specific specimen photographed in the associated auction archives, while noting that independent verification of the movement and specific technical configuration remains an ongoing research requirement.

Object description

Case and Dial Construction

The timepiece features a distinct octagonal case geometry, which is fabricated from 18K yellow gold. The architecture of the case is defined by a stepped bezel, which contributes to the structural silhouette of the watch.

The dial is finished in a silvered tone, serving as a neutral backdrop for the black Roman numeral hour markers. The layout is dominated by the perpetual calendar functions, which are presented via several sub-dials. A notable artistic feature is the moon-phase display located in the upper portion of the dial, which is crafted from a lapis lazuli stone disc.

Evidence for this section
  • “Housed in an elegant octagonal 18K yellow gold case with stepped bezel”
  • “The clean silvered dial is enhanced by black Roman numerals and a striking lapis lazuli moon-phase display”

Movement and Complications

The watch is powered by a manually wound movement. This caliber integrates two complications: a perpetual calendar system and a minute repeater mechanism. The calendar displays information such as the day, date, and month, requiring adjustments only for leap years or according to the specific perpetual mechanism integrated.

The minute repeater function provides the auditory report of time on demand. When activated, the watch strikes the hours, quarters, and minutes.

Evidence for this section
  • “The manually wound movement incorporates a perpetual calendar and minute repeater, striking the hours, quarters and minutes on demand”

Documentation and Attribution

This object is catalogued based on its appearance in an auction record, which attributes the production of the timepiece to the designer Gérald Genta. The date of production is placed by the source at circa 1990. The record serves as an educational reference for this specific specimen as it was documented in archival listings.

The auction description serves as the primary source for the physical attributes noted in this record. As with all archival records derived from auction data, independent confirmation of the specific internal movement configuration and mechanical type remains necessary for comprehensive verification beyond the provided auction-house summary.

  • “Independent confirmation of type attribution and auction-house statements remains research required.”

Open research questions
