The hand-drawn hairspring must show irregular natural geometry under magnification; machine-regular geometry means the hairspring has been replaced.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| movement | Hand-drawn hairspring geometry | Hairspring geometry shows natural hand-work irregularity visible under loupe | Machine-regular hairspring geometry; replacement or non-genuine hairspring |
| movement | Overall hand-built finishing | Approximately 95% of components hand-built; consistent with Hand Made 1 documentation | Machine-finished components inconsistent with the hand-built standard |
| caseback | Movement access for hairspring inspection | Hairspring visible and accessible for geometry inspection | Hairspring obscured or inaccessible for verification |
