Case 13 — 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.
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.
Request open and closed views from both sides, with the watch supported safely. Separate cosmetic alignment from whether the clasp engages reliably; functional concerns need hands-on inspection.
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.
Measure the lug opening and document bar diameter, shoulder position and strap thickness. Avoid forcing an assembly that does not fit and let a watchmaker check uncertain clearances.
Case 11 — Magnetism and rate: record evidence before naming a cause
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “Record the change and the circumstances without treating…” 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.
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.
Clarification for “Strap compatibility: width is only the first measurement”: the point beginning “Measure the lug opening and document bar diameter,…” 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 37 — Maintenance question: how do I tell if an automatic actually needs service? · source wording exercise
Correction note for “Maintenance question: how do I tell if an automatic actually needs service?”: retain the wording beginning “Useful signs, in rough order of seriousness: power reserve noticeably shorter…” 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.
Case 47 — What a water-resistance claim does and does not establish · source wording exercise
Limit of the answer in “What a water-resistance claim does and does not establish”: “A photograph or a caseback engraving is not…” 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.
Method note for “What a water-resistance claim does and does not establish”: use “A photograph or a caseback engraving is not…” 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.
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.
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: scope. Keep the stated question separate from any broader claim.
Case 42 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve · source wording exercise
Method note for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: use “Two watches from different brands can share the same caliber…” 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 21 — Service enquiry: information a watchmaker can use
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.
