Suggested protocol. 1) Both dials in one frame. 2) Diffuse daylight, no direct sun, plus a second shot under neutral indoor light. 3) Grey card visible. 4) No filters, no editing. 5) State camera settings if known. If both shots show the same direction of difference, the claim is supported. If the difference flips between lighting conditions, it's most likely lighting.

Method note for “First QC request: the minimum useful information”: use “State the model configuration, the specific concern and…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
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 7 — 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 11 — Forum comparison archive: link the evidence and the correction
A comparison has been corrected after a new photograph arrived. How should the original thread remain useful?
Exercise RWF-24433/11: address this question within its stated limits.
Clarification for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: the point beginning “First identify the caliber, lift-angle setting, winding…” 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 8 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
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.
Clarification for “Lume comparison: keep exposure and charging conditions consistent”: the point beginning “Treat the comparison…” 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 49 — What a water-resistance claim does and does not establish · source wording exercise
A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A photograph or a caseback engraving is not…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-19445/49: address this question within its stated limits.
Case 3 — Maintenance question: how do I tell if an automatic actually needs service?
Sealing and movement performance are separate questions. Ask a qualified watchmaker about inspection and testing appropriate to the particular watch and its intended use; a healthy rate does not establish water resistance.
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “Ask for photographs with the light moved and…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
Case 11 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The reported numbers alone do not establish damage or the need for service. Confirm the setup, collect comparable readings and ask a watchmaker to assess a concerning or changing pattern.
Case 4 — Comparing dial colour under different lighting
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?
Exercise RWF-13522/4: address this question within its stated limits.
Case 39 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained · source wording exercise
Summary draft for “Strap dimensions: lug width, taper, thickness and spring bar diameter explained”: the answer addresses “Measure with a ruler marked in millimetres, ideally…”; the related point is “Most watches use even numbers (18, 20, 22mm),…”. 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.
Clarification for “Maintenance question: how do I tell if an automatic actually needs service?”: the point beginning “The calendar interval is a conservative…” belongs to the question as written.
