Department policy / The small print that matters

How a guide earns its place.

Source it.

Original manufacturer documentation is primary. Experienced watchmakers may supplement it when the evidence is independently corroborated.

Mark the limits.

Every guide declares its movement variants, issue date, revision, bench status and safety hold points. Drafts are identified as drafts.

Improve the record.

Documented corrections produce a new revision. Older PDFs are never silently presented as the latest release.
