Case and Visual Configuration

The watch is an open-face pocket watch measuring 50 mm in diameter and 13 mm in depth. In the accompanying photographs, the watch displays an arched bow at the 12 o'clock position holding a fluted winding crown, as well as milled bezel edges around the case perimeter. The vendor notes that the housing is a Model A 10K gold-filled case with a screw-off back and bezel, featuring a smooth plain finish on the back. The dial is described in source text as a double-sunk white paint-on-metal dial, fitted beneath a mineral glass crystal. The dial displays bold black Arabic numerals, an outer minute track, and a subsidiary seconds dial at the 6 o'clock position, and bears the signature 'Hamilton 23 Jewels Railway Special'. Setting is executed via a lever mechanism, and the piece is stem wound.

Reported Movement Specifications

Movement specifications are drawn entirely from dealer statements, as the internal movement is concealed by the closed case back in visible imagery. The movement is reported as a 16-size, 23-jewel Grade 950B nickel bridge model 6 movement with serial number S19831, attributed by the seller to circa 1953. The vendor states the caliber is inscribed 'Hamilton Watch Co, USA, Adj temp & 6 positions, 950B, 23 Jewels' and is jewelled to the mainspring. Additional movement characteristics reported by the seller include a lever escapement with a micrometer regulator, gold-capped escape wheel and lever, gold jewel settings, and an Elinvar Extra hairspring.

Packaging and Documentation Evidence

The pocket watch is accompanied by two storage cases shown in documentation images: an outer blue textured cardboard box stamped 'HAMILTON' and an inner cream-colored Bakelite flip-top box resembling a cigarette case. The vendor indicates the cardboard box contains an interior label marked with a serial number corresponding to the watch. The Bakelite container features the Hamilton name on its lid and an applied crest on the front face. The seller notes minor fine abrasions on the case attributed to rubbing against the box lining during handling, as well as minor paint lines on the dial attributed to manufacture rather than post-production wear.
