## Prompt · English

```text
Depict a mechanical pocket watch as a vintage engineering plate on deep cobalt paper. Draw precise ivory linework for a central three-quarter view, an exploded assembly and two small cross-sections. Use sparse dimension arrows and these exact short labels: CASE; DIAL; GEARS; CROWN, with a discreet serial-number box. Keep the drawing elegant and mechanically plausible, with slight paper wear around the margins.
