Case 30 — Crystal reflections: why a dark patch is not a coating test
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “No single lighting setup settles…” 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.
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.
Case 11 — Disputed observation: is this dial colour shift real or just lighting?
Something to keep apart: sunburst and gradient dials can look like different colours depending on viewing angle, even on the same piece. A shift that appears only at certain angles is a finish effect, not a batch difference. Include a straight-on shot and one tilted shot so readers can tell the two apart.
Case 15 — QC photographs: perspective or a genuinely tilted index?
Summary draft for “QC photographs: perspective or a genuinely tilted index?”: the answer addresses “Request a level straight-on image with the hands…”; the related point is “Compare two independently aligned images before drawing a conclusion; an overlay…”. 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 56 — QC photography: what photos actually help verify a pre-owned listing? · source wording exercise
Summary draft for “QC photography: what photos actually help verify a pre-owned listing?”: the answer addresses “Flash flattens printing and hides…”; the related point is “Diffuse light shows print edges, alignment…”. 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.

The difficulty is that phone cameras adjust white balance automatically, and blue dials are especially sensitive. Two photos of the same dial under different light can easily look like a 'batch difference'. Any comparison needs both dials in the same frame, under the same light, ideally next to a neutral grey or white reference card.
Add a dated correction near the original conclusion and link the new evidence. Preserve the reasoning trail instead of silently replacing an uncertain claim with a confident one.
Record lug-to-lug and the effective span including rigid end links. Use a similar camera distance and neutral wrist position; photographs support fit discussion but do not replace measurements.
Thickness matters more than people expect. Straps around 4 to 5mm at the lugs can hit the case or stop the strap folding down on watches with short lugs or tight lug-to-case clearance. Do you know whether your watch has drilled lugs or a tight gap between strap and case? That tells you how much thickness is safe.
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.
Case 14 — QC photography: what photos actually help verify a pre-owned listing?
A caution: photos can't settle everything. Water resistance, timekeeping and internal condition aren't visible in any image. A short timegrapher video or a stated recent rate test adds information, but treat it as a seller claim unless an independent party confirms it. Photos narrow the risk. They don't remove it.
Case 17 — Service enquiry: information a watchmaker can use
Summary draft for “Service enquiry: information a watchmaker can use”: the answer addresses “Document when it stops, winding behaviour, recent impacts and…”; the related point is “Be honest about the watch and request an assessment…”. 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 49 — First QC request: the minimum useful information · source wording exercise
What should an initial QC request include so replies can address the actual question?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Include complete instrument settings where relevant and say…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-13560/49: address this question within its stated limits.
Method note for “A maintenance log that remains useful after a sale”: use “Keep the date, work performed, provider invoice reference…” 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.
