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.
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
Clarification for “Forum comparison archive: link the evidence and the correction”: the point beginning “Add a dated correction near the original conclusion…” 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.
Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
Clarification for “Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?”: the point beginning “Start with how you…” 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 27 — QC photography: what photos actually help verify a pre-owned listing?
Ask for a straight-on dial photo with diffuse light and no flash, the full dial in frame, and the hands placed away from the indices (10:10 isn't ideal, because it covers the upper markers). Flash flattens printing and hides lume condition. Diffuse light shows print edges, alignment and any spotting.
Case 9 — Magnetism and rate: record evidence before naming a cause
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Exercise RWF-00635/9: address this question within its stated limits.
