Case 15 — Crown operation: when a forum cannot diagnose the resistance
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Exercise RWF-28092/15: address this question within its stated limits.
Case 15 — Lug-to-lug and end-link overhang in wrist photographs
Limit of the answer in “Lug-to-lug and end-link overhang in wrist photographs”: “Record lug-to-lug and the effective span…” 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 15 — Case finishing: distinguish a reflection from a surface mark
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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.
Clarification for “Comparing dial colour under different lighting”: the point beginning “State the lighting 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 — Reading a timegrapher recording without losing the context
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 53 — QC photography: what photos actually help verify a pre-owned listing? · source wording exercise
Clarification for “QC photography: what photos actually help verify a pre-owned listing?”: the point beginning “Flash flattens printing and hides…” 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: source wording. Retain the source wording beside any paraphrase.
Case 33 — 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?
Exercise RWF-19469/33: address this question within its stated limits.
Start with function, legibility, assembly and clear visible damage. Explain what the full-size image shows, what the crop adds and what remains uncertain; do not turn an overlay into an automatic verdict.
Case 32 — Lug-to-lug and end-link overhang in wrist photographs
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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.
Case 16 — 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 29 — 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 5 — First QC request: the minimum useful information
What should an initial QC request include so replies can address the actual question?
Exercise RWF-09752/5: address this question within its stated limits.
Case 8 — 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.
