Design
- Visible features
- • White enamel dial with black Roman numeral hour markers and two subsidiary scales. • Central gold-toned hands with a blued steel hand visible on the upper subsidiary dial. • Dial inscription reads 'BARRAUD, INV. ET FEC.' and 'LONDON' near the lower section. • Elongated brass pendant stem with a flared collar extending from the top of the brass frame. • An oval brass tag bearing the accession number '1930 154' is attached near the bottom edge.
- Dial Display and Inscriptions
- The assembly features a circular white enamel dial fitted with central gold-toned hands along with two subsidiary scales. Black Roman numeral hour markers ring the perimeter, and a blued steel hand is visible on the upper subsidiary dial. Visible on the dial face near the lower section are the inscriptions 'BARRAUD, INV. ET FEC.' and 'LONDON'. The underlying gearing and specific complications related to these displays are not visible from the dial-facing viewpoint.
- Mechanical Mount and Visible Frame
- The dial is mounted within a brass chassis that houses the movement. An elongated brass pendant stem featuring a flared collar extends directly outward from the top of the brass frame. Attached near the bottom edge of the assembly is an oval brass tag stamped with the accession number '1930 154'. Screws remain positioned along the perimeter, though internal components such as the repeating striking train, escapement, and balance are not visible from this angle.
- Object Classification and Museum Identity
- This artifact represents a repeating pocket watch movement preserved under object number 1930-154. Recorded by the Science Museum Group under the category of Time Measurement and type 'pocket watch', the movement is credited to Mr. H. W. Ravenshaw. The museum records its maker as the Barraud family, dating production to 1780-1810 in London. The complete object measures 18 mm in depth, 51 mm in width, and 80 mm in height, with an overall recorded weight of 0.08 kg. Listed materials comprise enamel, brass (copper, zinc alloy), and steel (metal). As catalogued, the artifact consists of the movement assembly and dial rather than a complete, cased watch.
