Case 38 — What a water-resistance claim does and does not establish · source wording exercise
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “A photograph or a caseback engraving is not…” 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.
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “A competent watchmaker can test and diagnose it; random adjustment…” 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 28 — What a water-resistance claim does and does not establish
Summary draft for “What a water-resistance claim does and does not establish”: the answer addresses “Ask a qualified watchmaker about a suitable test for that individual…”; the related point is “A photograph or a caseback engraving is not…”. 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.
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.
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.
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.
Case 21 — What a water-resistance claim does and does not establish
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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 36 — Movement identification: the limits of a rotor photograph
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Case 15 — A maintenance log that remains useful after a sale
Correction note for “A maintenance log that remains useful after a sale”: retain the wording beginning “Keep the date, work performed, provider invoice reference…” 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 33 — QC checklist: prioritise observable faults over pixel hunting
Limit of the answer in “QC checklist: prioritise observable faults over pixel hunting”: “Start with function, legibility, assembly and…” 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.
Correction note for “Shipping timeline: separate dispatch, handover and scan events”: retain the wording beginning “Distinguish label creation from physical acceptance and retain dated…” 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 36 — Strap compatibility: width is only the first measurement
Summary draft for “Strap compatibility: width is only the first measurement”: the answer addresses “Measure the lug opening and document bar diameter,…”; the related point is “Avoid forcing an assembly that does not fit and…”. 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.
Record the change and the circumstances without treating the suspected cause as established. A competent watchmaker can test and diagnose it; random adjustment is not a substitute for assessment.
Case 13 — Magnetism and rate: record evidence before naming a cause
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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 — Packing photographs: document condition without exposing an address
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.
