Object description

Case Architecture and Enamel Decoration

The timepiece is an open-face pocket watch in yellow gold reported by the seller to measure 45 mm in diameter and crafted in 18K yellow gold. Visually, the front bezel and pendant neck display a continuous decorative band of black enamel in a Greek meander (key) pattern.

The seller reports that the reverse of the case is decorated with an engraved monogram bearing the initials 'S J F' and lists case number 265746. However, because only the front view is provided in the reference photograph, the reverse monogram, inner case hallmarks, and case serial number are not visible in the available documentation.

Reported Movement and Retail Attribution

Open research questions

  • What specific caliber layout, bridge design, and serial numbering are revealed upon opening the pocket watch case back?
  • Does the movement bridge carry Tiffany & Co. retailer engravings alongside Patek Philippe hallmarks?
  • Do internal case back stamps corroborate the 18K gold standard and case serial number 265746?
  • Can an Extract from the Archives from Patek Philippe confirm movement number 160776 and case number 265746 with a circa 1914 sale date to Tiffany & Co.?
