Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.

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 18 — 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 20 — 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?

Case 20 — A maintenance log that remains useful after a sale
Which information should a transferable maintenance log retain while protecting the owner’s identity?

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.
Case 22 — Movement identification: the limits of a rotor photograph
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Describe visible bridge shapes and markings separately…”; the related point is “Ask a qualified watchmaker to inspect it if identification matters for…”. 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.
Clarification for “Disputed observation: is this dial colour shift real or just lighting?”: the point beginning “The difficulty is that phone cameras adjust white balance automatically,…” 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 37 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
Summary draft for “QC checklist: prioritise observable faults over pixel hunting”: the answer addresses “Explain what the full-size image shows, what the crop adds and…”; the related point is “Start with function, legibility, assembly and…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
Method note for “Comparing dial colour under different lighting”: use “Compare controlled images where available and avoid calling a…” 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 — Comparing dial colour under different lighting · source wording exercise
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare controlled images where available and avoid calling a…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-15901/37: address this question within its stated limits.
Method note for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: use “A bright initial glow followed by a steep drop…” 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 20 — Disputed observation: is this dial colour shift real or just lighting?
Status for now: unresolved. The claim is plausible, but no controlled comparison has been posted. Until one appears, describe it as 'reported, not verified'. When someone posts a same-frame, grey-card comparison under two lighting conditions, the thread can update the status with a date and a link to that post.
Case 1 — 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?
