Reader check for “Crystal reflections: why a dark patch is not a coating test”: distinguish the discussion point “No single lighting setup settles…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.

Case 39 — Comparing dial colour under different lighting · source wording exercise
Limit of the answer in “Comparing dial colour under different lighting”: “Compare controlled images where available and avoid calling a…” 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 5 — Movement identification: the limits of a rotor photograph
Clarification for “Movement identification: the limits of a rotor photograph”: the point beginning “Describe visible bridge shapes and markings separately…” 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 14 — QC photography: what photos actually help verify a pre-owned listing?
When asking a seller for extra photos of a pre-owned watch, what shots are actually useful as evidence? Listings tend to have glossy angled photos that hide more than they show. I'd like a standard request list the forum can reuse.
Exercise RWF-25839/14: address this question within its stated limits.
First identify the caliber, lift-angle setting, winding state and measurement position. Without those fields, the rate, amplitude and beat-error values lack enough context for a useful comparison.
Request open and closed views from both sides, with the watch supported safely. Separate cosmetic alignment from whether the clasp engages reliably; functional concerns need hands-on inspection.
Case 23 — Maintenance question: how do I tell if an automatic actually needs service?
Keep a baseline log, describe changes in rate or running time and stop forcing rough winding. Follow the manufacturer’s guidance and arrange professional assessment when operation changes. A forum cannot prescribe a universal service interval.
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.

Case 51 — Lug-to-lug and end-link overhang in wrist photographs · source wording exercise
Method note for “Lug-to-lug and end-link overhang in wrist photographs”: use “Use a similar camera distance and neutral wrist position; photographs support…” 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. Retain the source wording beside any paraphrase.
Case 5 — First QC request: the minimum useful information
Method note for “First QC request: the minimum useful information”: use “State the model configuration, the specific concern 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.
Use fields for order date, promised terms, dated communications, delivery evidence and resolution. Leave unsupported fields blank and separate observations from opinions; this reference is not a seller endorsement.
Case 29 — Reading a timegrapher recording without losing the context
Correction note for “Reading a timegrapher recording without losing the context”: retain the wording beginning “Keep the complete recording and ask for the…” 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.
Method note for “Comparing versions without mixing case sizes”: use “List confirmed differences separately from seller descriptions and date the comparison…” 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.
Suggested protocol. 1) Both dials in one frame. 2) Diffuse daylight, no direct sun, plus a second shot under neutral indoor light. 3) Grey card visible. 4) No filters, no editing. 5) State camera settings if known. If both shots show the same direction of difference, the claim is supported. If the difference flips between lighting conditions, it's most likely lighting.
