- Dial and Case Construction
- The pocket watch is housed in an open-face Keystone fine silver case measuring 51 mm in width by 15 mm in depth. In the photograph, the silver-toned case shows a coin-edged bezel, a fluted crown, and a shaped bow, while the dealer reports turned sides, a smooth plain finish, a mineral glass crystal, and screw-off front and back bezels. The dial is described by the dealer as black paint on metal, bearing white hands including a central sweep seconds hand. The visual display presents an inner 1 to 24 hour numeral track and outer minute or seconds markings, with the dealer noting the hands make one revolution every 24 hours. The dial is signed 'GCT'.
- Reported Movement and Mechanism
- The internal movement is not visible in the provided photograph, and all movement specifications derive solely from the dealer description. The seller reports a 16-size, stem-wound and stem-set nickel three-quarter plate movement equipped with a lever escapement and a micrometer regulator. According to the dealer, an extra wheel and jewel on the top plate raise the jewel count to 22 jewels. The movement is also reported to feature a hacking mechanism that arrests the balance when setting the hands, with the plate engraved 'Hamilton Watch Co, USA, 4992B, 22 Jewels, US Govt, Adj Temp & 6 positions' and numbered 4C28840.
- Packaging and Documentation Discrepancies
- The pocket watch is photographed resting on a printed military cardboard container bearing the text 'WATCH; NAVIGATION, MASTER', 'Mfr's. Part No. 4992B', and 'HAMILTON WATCH COMPANY'. The seller notes that although the watch and box accompanied one another, the handwritten number on the front of the box reads '4037-42', which differs from the reported movement serial number 4C28840.
