Case 17 — 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 18 — 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.

Case 18 — 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.

Case 18 — Crown operation: when a forum cannot diagnose the resistance

Method note for “Crown operation: when a forum cannot diagnose the resistance”: use “Describe whether resistance occurs during winding or setting 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.

Case 18 — Crown operation: when a forum cannot diagnose the resistance

Limit of the answer in “Crown operation: when a forum cannot diagnose the resistance”: “Describe whether resistance occurs during winding or setting 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 18 — Crown operation: when a forum cannot diagnose the resistance

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.

Case 19 — Case finishing: distinguish a reflection from a surface mark

A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?

Exercise RWI-20169/19: address this question within its stated limits.

Case 19 — Case finishing: distinguish a reflection from a surface mark

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 20 — Comparing versions without mixing case sizes

Two purported versions differ in case diameter and bracelet. How can the comparison avoid attributing every difference to a revision?

Exercise RWI-20169/20: address this question within its stated limits.

Case 20 — Comparing versions without mixing case sizes

Match reference, dimensions and configuration first. List confirmed differences separately from seller descriptions and date the comparison so later readers understand its scope.
