- Identity and Attribution
- The object is recorded in the Science Museum Group Collection as a duplex pocket watch attributed to Benjamin Lewis Vulliamy and made in London. The collection title dates the object to 1810-1823, with a specific record noting it was hallmarked in 1823. Catalogued under object number 1916-182, the watch entered the collection with credit to Mr. Evan Roberts. A descriptive caption in the source record identifies it as a 'Duplex watch in gilt silver hunter case by Vulliamy, London, no.xx a m. Hall marked 1823'.
- Dial Presentation and Movement
- The visible dial is executed in white enamel with black Roman numeral hour indices. An off-centre subsidiary seconds register is positioned between the 7 and 8 o'clock markers, and a maker signature inscription appears directly below the 12 o'clock position. The collection catalogues the object as both a 'pocket watch' and a 'duplex watch'. However, the internal duplex movement mechanism is not exposed in the visual record, and its mechanical details remain source-reported rather than directly verifiable from the photograph.
- Case Construction and Dimensions
- Direct visual observation confirms that the front hinged hunter lid is open, displaying internal hallmarks stamped into the metal. The case perimeter relative to the dial orientation features a rounded pendant and a circular suspension bow mounted at approximately 4 to 5 o'clock. According to the source documentation, the overall dimensions in an open configuration are 70 mm by 80 mm by 55 mm, with a recorded weight of .15kg. Stated materials for the piece include silver, gilding, brass, enamel, and springs.
