Dial and Visual Appearance
The pocket watch displays an open-face configuration with a single-sunk Montgomery-style melamine dial signed 'Hamilton, Railway Special'. Visible dial elements include distinct Arabic hour numerals, a continuous perimeter minute track with individual Arabic figures, and a subsidiary seconds register positioned at 6 o'clock. Time is indicated by a pair of blue steel hands. The timepiece measures 50 mm across by 15 mm deep. Visible around the front bezel is a milled outer border accented by repeating raised circular motifs, with the winding crown and bow positioned directly above 12 o'clock. The seller reports that the watch is fitted with a flat bulls-eye glass.
Reported Movement and Construction
According to the seller's description, the movement is a 16-size high-grade nickel bridge grade 950B mechanism bearing serial number S21608. The dealer states it features 23 jewels, gold jewel settings, a micrometer regulator, a lever escapement, and a gold-capped escape wheel and lever. The listing notes it is jewelled to the mainspring, utilizes an Elinvar Extra hairspring, and is stem-wound and lever-set. The movement decoration is described as having pinstripe damascening on the bridges and circular damascening on the winding wheels. Engraved bridge text is transcribed by the dealer as 'Hamilton Watch Co, USA, Adj temp & 6 positions, 950B, 23 Jewels' alongside serial number S21608.
Case Details and Source Limitations
The movement is housed in what the listing terms a Model A 10K gold-filled open-face case fitted with a screw-off back and bezel. The exterior features milled edges and raised circular motifs, with a smooth plain finish reported on the case back. Wear noted in the listing includes light scratches on the case back and deep marks on one small raised circle on the back bezel. Because the provided photograph only displays the front dial side, all movement descriptions—including the caliber grade, jewel settings, damascening, and serial number S21608—rely solely on the dealer's catalog text. In addition, the source provides conflicting production dates, listing 'c1957' in the listing title while stating 'circa 1952' in the item description.

Research required

  • Research required: The source provides conflicting dates: c1957 in the listing title and circa 1952 in the body description.
  • Research required: Movement details and serial number cannot be verified from the image as only the dial side is shown; details rely entirely on dealer statements.
