Object description

Case Construction and Enamel Ornamentation

The pendant pocket watch is catalogued as being crafted in 18 ct gold, measuring 2.5 cm in diameter and weighing a total of 18.3 grams. Visual observation of the reverse shows bright blue translucent enamel laid over engine-turned concentric wavy guilloché patterns, with a yellow gold winding stem, a ribbed fluted crown, and visible hinge elements.

Embellishment across the exterior incorporates diamond settings. The case back is documented as being decorated with diamond-set appliqués on a blue enameled background, visible as three floral-shaped appliqués framed by inner and outer concentric diamond-set borders. The auction description additionally states that the arched bail and the bezel are also set with diamonds.

Evidence for this section
  • “LECOULTRE & CIE, ANTIQUE DIAMOND AND ENAMEL POCKET WATCH, in 18 ct gold.”
  • “The back of the watch decorated with diamond set appliques on a blue enameled background.”
  • “The bail and bezel also set with diamonds.”
  • “Diam. 2.5 cm. 18.3 grams.”
  • “Bright blue translucent enamel over concentric engine-turned wavy guilloché patterns on the case back”
  • “Outer border, inner ring, arched decorative bail, and three central floral-shaped appliqués set with small diamonds”

Reported Dial and Movement Configuration

The catalog notes that the watch features a manual-winding movement signed 'LeCoultre & Cie.' The front of the watch is reported to have a white enameled dial with Arabic numbers.

The movement, inner cuvette, and dial are not depicted in the single catalog photograph, which presents only the reverse exterior of the case. Specific movement caliber designations, jewel counts, and operational performance are not recorded in this source.

Evidence for this section
  • “White enameled dail with Arabic numbers.”
  • “Manual winding. Movement signed: LeCoultre & Cie.”

Auction Context and Documentation Scope

The watch was offered as lot 69 by Etrusca Auctions Ltd in their sale on 28th January 2022. While the catalog title designates the piece as an antique pocket watch, no specific production year, serial number, or hallmarking records are provided in the listing text.

Because visual documentation is restricted to the decorated case back and stem/bail assembly, descriptions of the front dial, bezel diamond setting, and internal movement signatures remain source-reported claims from the auctioneer rather than independently verifiable details.

Evidence for this section
  • “LECOULTRE & CIE, ANTIQUE DIAMOND AND ENAMEL POCKET WATCH sold at auction on 28th January”
  • “Lot 69”
  • “Jan 28, 2022”

Open research questions

  • What specific caliber number and movement serial number are stamped on the internal plates?
  • What gold hallmarks or casemaker sponsor marks are present inside the case back or cuvette?
  • What is the hand style and visual preservation state of the reported white enameled dial?
