- Visible features
- • Damascened nickel bridge plates with black-filled engravings and brass train wheels • Balance cock fitted with a fine adjustment micrometer regulator marked with F and S • Open-face chromium-plated nickel case with shaped bow and fluted winding crown
- Construction and Housing
- The watch is housed in an open-face, chromium-plated nickel case featuring a flat, shaped bow and a winding/setting crown integrated into a wide pendant. Pulling the winding button activates a stop-work mechanism and enables hand-setting. A convex, unbreakable glass is secured by a knurled, screw-down bezel. The nickel case back is machine-engraved with 'H.S. 3' and '2058'. The interior of the case back is stamped 'STAR WATCH CASE CO.', 'BASE METAL', and the assembly number 'P648017'.
- Provenance and Documentation
- The watch is contained in a mahogany deck box featuring a circular glazed 'porthole' on the lid. The box is lined with imitation leather and contains a black-painted aluminium label identifying the watch as 'Stores Ref. H.S.527-3637' with the serial number '2058'. The movement serial number (3C2483) does not match the case and box serial number (2058). The source suggests this discrepancy likely arose from the interchangeability of Hamilton movements during military workshop overhauls.
- Movement Technical Specification
- The watch utilizes a Hamilton calibre 3992 B movement, which is a damascened, nickel-plated, barred caliber with a going barrel. The movement features 22 jewels with red stones in press-in brass settings and a centre seconds drive off the third wheel. The escapement is a double-roller, jewelled, club-tooth lever type. The uncut balance is equipped with 20 brass screws and a 'Hamilton Elinvar Extra' flat spiral balance spring with an overcoil. Fine adjustment is managed via a polished steel index on the balance cock, marked with 'F' and 'S'.
