Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.

Case 31 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Exercise RWF-30406/31: address this question within its stated limits.
Case 42 — Clasp photographs: what to request before judging alignment · source wording exercise
Reader check for “Clasp photographs: what to request before judging alignment”: distinguish the discussion point “Separate cosmetic alignment from whether the clasp engages reliably;…” 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.
Case 9 — First QC request: the minimum useful information
What should an initial QC request include so replies can address the actual question?

Case 39 — Service enquiry: information a watchmaker can use · source wording exercise

Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.
Case 13 — Crystal reflections: why a dark patch is not a coating test
No single lighting setup settles that question. Compare multiple controlled angles and describe the visible observation without asserting material specifications that have not been verified.

Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Case 20 — Lume comparison: keep exposure and charging conditions consistent
Limit of the answer in “Lume comparison: keep exposure and charging conditions consistent”: “Treat the comparison…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.

Case 5 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Lume photos are close to useless for comparison unless exposure is fixed. Phones raise exposure automatically in the dark, so a dim watch can look as bright as a strong one. For a fair photo comparison: same charge method, same delay after charging, manual exposure, and both watches in the same frame.
Case 29 — Reading a timegrapher recording without losing the context

Case 20 — Disputed observation: is this dial colour shift real or just lighting?
Something to keep apart: sunburst and gradient dials can look like different colours depending on viewing angle, even on the same piece. A shift that appears only at certain angles is a finish effect, not a batch difference. Include a straight-on shot and one tilted shot so readers can tell the two apart.
Case 44 — Movement identification: the limits of a rotor photograph · source wording exercise
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Ask a qualified watchmaker to inspect it if identification matters for…”; the related point is “Describe visible bridge shapes and markings separately…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
