Reported Movement Specifications
Because the provided visual record shows only the front of the watch, all movement specifications are derived strictly from dealer reporting. The seller states that the watch contains an open-face, stem-wound and lever-set mechanism designated as a Hamilton grade 950B, bearing the movement serial number S18112. According to the listing, the nickel bridge movement incorporates 23 jewels (jewelled to the mainspring), a lever escapement, gold jewel settings, a micrometer regulator, and a gold-capped escape wheel and lever. The seller reports it is signed 'Hamilton Watch Co, USA, Adj temp & 6 positions, 950B, 23 Jewels' and fitted with an Elinvar Extra hairspring.
Visual Dial and Case Configuration
The timepiece presents an open-face configuration with an off-white, single-sunk dial marked below the 12 o'clock position with the text 'HAMILTON / 23 JEWELS / RAILWAY SPECIAL'. Hour indications are rendered in bold black Arabic numerals encircled by an outer railroad minute track. A subsidiary seconds dial is positioned at 6 o'clock, with time displayed via blued steel spade hands. The movement is housed in a yellow-tone case measuring 50 mm in diameter and 14 mm in depth. Visible casework includes a screw bezel featuring milled or ribbed patterning, crowned by a top-winding stem and bow enclosing a bevelled mineral glass.
Case Specifications and Dating Limitations
The dealer identifies the housing as a 'model A, 10K Gold filled open face case' constructed with a screw-off bezel and back, characterized by milled edges and a smooth plain finish on the rear cover. Dating the piece to circa 1952 is entirely seller-asserted. As the movement and interior case markings are concealed in the listing photographs, independent verification of the movement serial, internal case hallmarks, and original factory pairing cannot be established from the documentation.
