Case 40 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
A large crop makes tiny differences look dramatic. How can a checklist remain proportionate?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Explain what the full-size image shows, what the crop adds and…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-28682/40: address this question within its stated limits.
Jewel count describes bearings used in a movement design; it is not a quality ranking. Compare the documented movement architecture and service support rather than assuming a higher count makes one watch better.
Limit of the answer in “Packing photographs: document condition without exposing an address”: “Photograph the item and protective packing…” 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 38 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
Correction note for “Crystal reflections: why a dark patch is not a coating test”: retain the wording beginning “Compare multiple controlled angles and describe the visible observation without asserting…” 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. Retain the source wording beside any paraphrase.
A useful table has columns for date, position, winding state, lift angle, rate, amplitude and beat error. Keep the full recording so settings and stability can be checked.
Case 15 — 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-21617/15: address this question within its stated limits.
Case 53 — Forum comparison archive: link the evidence and the correction · source wording exercise
Method note for “Forum comparison archive: link the evidence and the correction”: use “Preserve the reasoning trail instead of silently replacing an…” 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 32 — 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.
Limit of the answer in “Crystal reflections: why a dark patch is not a coating test”: “No single lighting setup settles…” 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.
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.
A correction to a common assumption: a slightly loose fit isn't automatically wrong. Heavier heads tend to slide on loose bracelets, but a lighter watch often wears comfortably with a finger's width of space. Try 'loose' for a full day before deciding it doesn't work. Comfort over hours tells you more than the first minute.
Case 4 — 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.
Case 30 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
On anti-reflective coatings: inner-surface AR cuts glare without wear concerns. Outer-surface AR improves legibility further but can scuff over time, and the scuffs show up as hazy patches in certain light. When comparing two watches, check which surfaces are coated. Spec sheets often just say 'AR coated' without saying where.
Case 35 — 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.
Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.
