- Dial and Visual Presentation
- The pocket watch displays an open-face configuration with a white dial fitted with bold, stylized Arabic hour numerals and blued spade hands. A subsidiary seconds subdial sits at the 6 o'clock position, marked with Arabic numerals at ten-second increments and printed with the text 'SECOND SETTING DIAFLEX'. The upper portion of the dial is signed 'SEIKO PRECISION 15 JEWELS'. The listing notes minor surface spotting and light soiling across the dial surface. Direct visual observation records visible plating wear and minor chipping along the outer edge of the chromed bezel ring.
- Casing and Administrative Issue Markings
- The timepiece is housed in a chromed base-metal case measuring approximately 49.5 mm in diameter, extending to 63 mm including the crown and 71.6 mm with the bow ring, with an overall weight of approximately 98 grams. The crystal is described as a domed glass type showing fine surface scratches and light hazing. According to the listing description, the exterior caseback carries an engraved marking reading '私鉄 67 / 113'. The cataloguer associates this notation with an equipment issue for a private railway operator (私鉄, shitetsu), where 67 represents an issue number and 113 indicates a unit or lot.
- Reported Movement and Technical Characteristics
- The internal mechanism is reported in the listing text as a manual-winding mechanical movement bearing the 'SEIKOSHA' and '15 JEWELS' signatures on the plates. The cataloguer describes a finely striped mainplate, gold-toned wheels, jewels set in polished chatons, and a fast/slow regulator lever mounted on the balance cock. The dial's 'DIAFLEX' inscription is noted by the seller as referencing Seiko's proprietary anti-shock hairspring system. The listing reports that the movement was checked running flat (dial up) after a full wind, though long-term positional timing and accuracy are explicitly not guaranteed.
