Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” 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.

Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” 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.
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Case 27 — Crown operation: when a forum cannot diagnose the resistance
Clarification for “Crown operation: when a forum cannot diagnose the resistance”: the point beginning “Describe whether resistance occurs during winding or setting 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.
Clarification for “First QC request: the minimum useful information”: the point beginning “State the model configuration, the specific concern 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.
Correction note for “Crown operation: when a forum cannot diagnose the resistance”: retain the wording beginning “Describe whether resistance occurs during winding or setting 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.
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Case 14 — QC checklist: prioritise observable faults over pixel hunting
Limit of the answer in “QC checklist: prioritise observable faults over pixel hunting”: “Start with function, legibility, assembly 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: scope. Keep the stated question separate from any broader claim.
Case 32 — Crystal reflections: why a dark patch is not a coating test
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 26 — 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-16822/26: address this question within its stated limits.
Case 19 — QC photographs: perspective or a genuinely tilted index?
A marker can look tilted when the camera is above the dial axis. What extra image would separate perspective from an assembly issue?

Case 29 — 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.
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.
Case 17 — QC checklist: prioritise observable faults over pixel hunting
A large crop makes tiny differences look dramatic. How can a checklist remain proportionate?
