Case 26 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
A stated water-resistance rating does not establish the present condition of an individual watch. Separate the manufacturer specification from a dated inspection or test of the particular example.
Case 9 — QC checklist: prioritise observable faults over pixel hunting
Summary draft for “QC checklist: prioritise observable faults over pixel hunting”: the answer addresses “Start with function, legibility, assembly and…”; the related point is “Explain what the full-size image shows, what the crop adds and…”. 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 5 — 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.
Case 8 — Comparing dial colour under different lighting
Method note for “Comparing dial colour under different lighting”: use “State the lighting 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 “Lume questions: why does my lume fade so quickly, and how should I compare it?”: the point beginning “A bright initial glow followed by a steep drop…” 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 186 — Crown operation: when a forum cannot diagnose the resistance · correction exercise
Correction note for “Crown operation: when a forum cannot diagnose the resistance”: retain the wording beginning “Stop forcing it and arrange inspection rather than trying…” 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. Preserve the old wording if a later source changes the interpretation.
The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.
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.
Case 3 — A maintenance log that remains useful after a sale
Limit of the answer in “A maintenance log that remains useful after a sale”: “Keep the date, work performed, provider invoice reference…” 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 22 — QC checklist: prioritise observable faults over pixel hunting
A large crop makes tiny differences look dramatic. How can a checklist remain proportionate?
Exercise RWF-20816/22: address this question within its stated limits.
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “Match reference, dimensions and…”; the related point is “List confirmed differences separately from seller descriptions and date the comparison…”. 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 8 — Magnetism and rate: record evidence before naming a cause
Method note for “Magnetism and rate: record evidence before naming a cause”: use “Record the change and the circumstances without treating…” 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 37 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Limit of the answer in “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: “Sapphire is very hard to scratch but can chip or crack…” 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.
Case 47 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me? · source wording exercise
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Without those fields, the rate, amplitude and beat-error values lack…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-16049/47: address this question within its stated limits.
Clarifying question: what does daily wear mean for you? Desk work, manual labour or sports change the answer. For desk use, sapphire's scratch resistance is the main benefit. For work with frequent knocks, a slightly domed acrylic that you can polish may last longer in practice, despite the scratches.
