Case 31 — QC photographs: perspective or a genuinely tilted index?
Request a level straight-on image with the hands clear of the marker. Compare two independently aligned images before drawing a conclusion; an overlay cannot correct an oblique camera angle.
Case 222 — Crown operation: when a forum cannot diagnose the resistance · indexing exercise
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Review focus: indexing. Make the reasoning findable without reducing it to a trust score. Use the original answer fragment “Describe whether resistance occurs during winding or setting and…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25905/222: address this question within its stated limits.
Case 8 — Crown operation: when a forum cannot diagnose the resistance
Describe whether resistance occurs during winding or setting and whether the crown engages consistently. Stop forcing it and arrange inspection rather than trying an unverified repair from a thread.
Clarification for “QC checklist: prioritise observable faults over pixel hunting”: the point beginning “Start with function, legibility, assembly 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.
Correction note for “Maintenance question: how do I tell if an automatic actually needs service?”: retain the wording beginning “The calendar interval is a conservative…” 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.
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “Keep the complete recording and ask for the…” 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 44 — Magnetism and rate: record evidence before naming a cause · source wording exercise
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A competent watchmaker can test and diagnose it; random adjustment…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-18708/44: address this question within its stated limits.
Case 24 — QC photography: what photos actually help verify a pre-owned listing?
Clarifying question for the thread: is the goal to check authenticity, condition, or both? For condition, the request list above is enough. For authenticity, you also need caseback, serial or reference engravings, and ideally movement photos. Movement photos usually require opening the watch, which a seller may reasonably refuse without a watchmaker present.
Case 26 — A maintenance log that remains useful after a sale
Which information should a transferable maintenance log retain while protecting the owner’s identity?
Exercise RWF-16063/26: address this question within its stated limits.
Caliber is the movement's model designation, like a part number. Two watches from different brands can share the same caliber family with different finishing or regulation. On a spec sheet it tells you what's inside and roughly what service parts are available. It doesn't tell you how well that particular example was adjusted.
Case 31 — Maintenance question: how do I tell if an automatic actually needs service?
If the manufacturer provides a suitable procedure, a running-time log can support a service enquiry. State the winding method and stop time. A shortened run does not identify the cause by itself.
Case 40 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log · source wording exercise
Summary draft for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: the answer addresses “Diameter alone tells you little…”; the related point is “Two cases 2mm apart in diameter can be within 1mm of…”. 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.
Method note for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: use “Without those fields, the rate, amplitude and beat-error values lack…” 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.
The reported numbers alone do not establish damage or the need for service. Confirm the setup, collect comparable readings and ask a watchmaker to assess a concerning or changing pattern.
Clarification for “Clasp photographs: what to request before judging alignment”: the point beginning “Request open and closed views from both sides,…” 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.
