Case 37 — Movement identification: the limits of a rotor photograph · source wording exercise

Reader check for “Movement identification: the limits of a rotor photograph”: distinguish the discussion point “Ask a qualified watchmaker to inspect it if identification matters for…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.
