Case 10 — Comparing dial colour under different lighting
Summary draft for “Comparing dial colour under different lighting”: the answer addresses “State the lighting and…”; the related point is “Compare controlled images where available and avoid calling a…”. 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 14 — Comparing dial colour under different lighting
Clarification for “Comparing dial colour under different lighting”: the point beginning “State the lighting 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 47 — Case finishing: distinguish a reflection from a surface mark · source wording exercise
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A mark should be assessed across multiple views; aggressive polishing…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-29861/47: address this question within its stated limits.
Start with function, legibility, assembly and clear visible damage. Explain what the full-size image shows, what the crop adds and what remains uncertain; do not turn an overlay into an automatic verdict.

Case 28 — 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 157 — Packing photographs: document condition without exposing an address · uncertainty exercise
A condition record is useful but a shipping label contains personal information. How can the record be shared safely?
Review focus: uncertainty. Leave the unresolved part visible instead of supplying a result. Use the original answer fragment “Photograph the item and protective packing…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25905/157: address this question within its stated limits.
Case 28 — Crystal reflections: why a dark patch is not a coating test
Summary draft for “Crystal reflections: why a dark patch is not a coating test”: the answer addresses “No single lighting setup settles…”; the related point is “Compare multiple controlled angles and describe the visible observation without asserting…”. 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.
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 40 — Forum comparison archive: link the evidence and the correction · source wording exercise
Limit of the answer in “Forum comparison archive: link the evidence and the correction”: “Preserve the reasoning trail instead of silently replacing an…” 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.
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
Case 19 — Case finishing: distinguish a reflection from a surface mark
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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.
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 7 — Movement identification: the limits of a rotor photograph
Correction note for “Movement identification: the limits of a rotor photograph”: retain the wording beginning “Describe visible bridge shapes and markings separately…” 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 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.
