Design

Visible features
• Open-face pocket watch in a yellow gold-toned case with an engraved decorative bezel and bow • Single-sunk white dial with black Arabic numerals, an inner red 13–24 hour ring, blued hands, and subsidiary seconds at 6 o'clock • Upright cream Bakelite presentation case marked 'HAMILTON' vertically on the flip lid, with a crest on the lower body and a blue velvet interior
Dial and Visual Appearance
The pocket watch is configured in an open-face style beneath a mineral glass crystal. According to the seller, the white enamel dial features a single-sunk layout designed for the Canadian market, bearing an inner red enamel 24-hour chapter ring alongside a pair of blued steel hands and the signature “Hamilton”. Direct visual observation confirms a single-sunk white dial with black Arabic numerals for 1–12, an inner red track showing 13–24, blued hands, and a subsidiary seconds subdial at 6 o'clock. The yellow gold-toned case shows an engraved decorative bezel and matching bow.
Case Construction and Presentation Box
The listing reports that the movement is housed in a Model 11 10K gold-filled open-face case measuring 50 mm in diameter by 13 mm in depth. The case construction features a screw-off back and bezel, with milled edges and a smooth, plain finish across the reverse. The piece is accompanied by a cream Bakelite flip-top cigarette-style presentation box. The exterior of the box is signed “Hamilton” on the lid and displays a crest on the front body; its interior is lined with velvet, though the seller notes that the velvet is missing from the lid.
Reported Movement and Operating Mechanism
Because the case back is closed in the available photograph, movement details derive entirely from the seller's description. The seller describes the mechanism as a stem-wound, lever-set nickel bridge movement signed “Hamilton Watch Co, USA, Adj temp & 6 positions, 950B, 23 Jewels” with serial number S17508. The dealer further reports that the movement features 23 jewels, jewelling to the mainspring, a lever escapement, a micrometer regulator, a gold-capped escape wheel and lever, and gold jewel settings. The text notes that the 950B utilized an Elinvar Extra hairspring, though it also confusingly refers to an "Elinvar mainspring".
