Case 5 — Crown operation: when a forum cannot diagnose the resistance
Describe whether resistance occurs during winding or setting and whether the crown engages consistently. Stop forcing it and arrange inspection rather than trying an unverified repair from a thread.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “No single lighting setup settles…” 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.
Reader check for “QC checklist: prioritise observable faults over pixel hunting”: distinguish the discussion point “Explain what the full-size image shows, what the crop adds and…” 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: scope. Keep the stated question separate from any broader claim.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Case 34 — Comparing dial colour under different lighting
State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.
Case 13 — What a water-resistance claim does and does not establish
Limit of the answer in “What a water-resistance claim does and does not establish”: “Ask a qualified watchmaker about a suitable test for that individual…” 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.
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.
Limit of the answer in “Lug-to-lug and end-link overhang in wrist photographs”: “Record lug-to-lug and the effective span…” 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 15 — 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-23699/15: 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 18 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.
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. 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 29 — 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-16224/29: address this question within its stated limits.
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” 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.
Case 18 — QC photographs: perspective or a genuinely tilted index?
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Request a level straight-on image with the hands…” 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.
