Case 13 — Lug-to-lug and end-link overhang in wrist photographs
Correction note for “Lug-to-lug and end-link overhang in wrist photographs”: retain the wording beginning “Record lug-to-lug and the effective span…” 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.
Case 25 — Comparing versions without mixing case sizes
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “Match reference, dimensions and…”; the related point is “List confirmed differences separately from seller descriptions and date the comparison…”. 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 98 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained · comparison exercise
Clarification for “Strap dimensions: lug width, taper, thickness and spring bar diameter explained”: the point beginning “Most watches use even numbers (18, 20, 22mm),…” 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: comparison. Make the basis of a comparison explicit before interpreting it.
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.
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Distinguish label creation from physical acceptance and retain dated…” 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 — Reading a timegrapher recording without losing the context
Summary draft for “Reading a timegrapher recording without losing the context”: the answer addresses “Keep the complete recording and ask for the…”; the related point is “A single number cannot establish service condition, movement identity…”. 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 13 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Exercise RWF-21987/13: address this question within its stated limits.
Case 14 — QC photographs: perspective or a genuinely tilted index?
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Request a level straight-on image with the hands…” 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 52 — What a water-resistance claim does and does not establish · source wording exercise
A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A photograph or a caseback engraving is not…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-19694/52: address this question within its stated limits.
Case 12 — Lume comparison: keep exposure and charging conditions consistent
Two glowing dials are shown with different camera exposure and unknown charging time. What can the images establish?
Exercise RWF-18803/12: address this question within its stated limits.
Case 26 — Clasp photographs: what to request before judging alignment
Method note for “Clasp photographs: what to request before judging alignment”: use “Request open and closed views from both sides,…” 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.
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.
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” 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.
Document when it stops, winding behaviour, recent impacts and the positions in which it happens. Be honest about the watch and request an assessment before approving work or ordering parts.
