Case 31 — Maintenance question: how do I tell if an automatic actually needs service?
Keep a baseline log, describe changes in rate or running time and stop forcing rough winding. Follow the manufacturer’s guidance and arrange professional assessment when operation changes. A forum cannot prescribe a universal service interval.
Case 31 — Disputed observation: is this dial colour shift real or just lighting?
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.
Limit of the answer in “Comparing dial colour under different lighting”: “State the lighting and…” 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: source wording. Retain the source wording beside any paraphrase.
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 13 — Comparing versions without mixing case sizes
Clarification for “Comparing versions without mixing case sizes”: the point beginning “Match reference, dimensions and…” 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 10 — What a water-resistance claim does and does not establish
A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?
Exercise RWF-21140/10: address this question within its stated limits.
Clarification for “A maintenance log that remains useful after a sale”: the point beginning “Keep the date, work performed, provider invoice reference…” 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 33 — QC photography: what photos actually help verify a pre-owned listing?
A caution: photos can't settle everything. Water resistance, timekeeping and internal condition aren't visible in any image. A short timegrapher video or a stated recent rate test adds information, but treat it as a seller claim unless an independent party confirms it. Photos narrow the risk. They don't remove it.
Case 21 — Magnetism and rate: record evidence before naming a cause
Summary draft for “Magnetism and rate: record evidence before naming a cause”: the answer addresses “Record the change and the circumstances without treating…”; the related point is “A competent watchmaker can test and diagnose it; random adjustment…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.
Case 41 — Seller review template: facts, dates and unresolved questions · source wording exercise
Clarification for “Seller review template: facts, dates and unresolved questions”: the point beginning “Leave unsupported fields blank and separate observations from opinions; this…” 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: source wording. Retain the source wording beside any paraphrase.
Case 10 — Reading a timegrapher recording without losing the context
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “Keep the complete recording and ask for the…” 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.
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.
