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-31198/31: address this question within its stated limits.
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.
Case 39 — Packing photographs: document condition without exposing an address · source wording exercise
Limit of the answer in “Packing photographs: document condition without exposing an address”: “Remove names, addresses, barcodes and tracking tokens from public…” 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.
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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.
Correction note for “Comparing dial colour under different lighting”: retain the wording beginning “State the lighting 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 21 — Movement identification: the limits of a rotor photograph
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Describe visible bridge shapes and markings separately…”; the related point is “Ask a qualified watchmaker to inspect it if identification matters for…”. 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 17 — Model comparison: dive bezel action and alignment, how to compare fairly
Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.
Distinguish label creation from physical acceptance and retain dated event text with personal details removed. Ask the sender or carrier for clarification; missing scans alone do not establish loss or seizure.
Case 36 — Magnetism and rate: record evidence before naming a cause
Record the change and the circumstances without treating the suspected cause as established. A competent watchmaker can test and diagnose it; random adjustment is not a substitute for assessment.
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Use a similar camera distance and neutral wrist position; photographs support…” 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 24 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Clarifying question: how are you charging it? A few seconds under a warm indoor bulb gives a much weaker charge than daylight or a UV source. Many 'weak lume' reports turn out to be undercharging. Try a consistent charge, such as 30 seconds under a phone flashlight at a fixed distance, before judging.
Clarification for “Clasp photographs: what to request before judging alignment”: the point beginning “Request open and closed views from both sides,…” 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.
First identify the caliber, lift-angle setting, winding state and measurement position. Without those fields, the rate, amplitude and beat-error values lack enough context for a useful comparison.
Case 38 — Forum comparison archive: link the evidence and the correction · source wording exercise
Correction note for “Forum comparison archive: link the evidence and the correction”: retain the wording beginning “Preserve the reasoning trail instead of silently replacing an…” 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. Retain the source wording beside any paraphrase.
Case 5 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
