Case 39 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log · source wording exercise
Correction note for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: retain the wording beginning “Diameter alone tells you little…” 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 51 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
Correction note for “QC photographs: perspective or a genuinely tilted index?”: retain the wording beginning “Compare two independently aligned images before drawing a conclusion; an overlay…” 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 16 — Movement identification: the limits of a rotor photograph
Limit of the answer in “Movement identification: the limits of a rotor photograph”: “Describe visible bridge shapes and markings separately…” 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.
Clarification for “Comparing versions without mixing case sizes”: the point beginning “Match reference, dimensions 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.
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.
Summary draft for “Forum comparison archive: link the evidence and the correction”: the answer addresses “Preserve the reasoning trail instead of silently replacing an…”; the related point is “Add a dated correction near the original conclusion…”. 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 “QC photographs: perspective or a genuinely tilted index?”: “Request a level straight-on image with the hands…” 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.
The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.
Case 13 — Shipping timeline: separate dispatch, handover and scan events
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 19 — Strap compatibility: width is only the first measurement
Method note for “Strap compatibility: width is only the first measurement”: use “Measure the lug opening and document bar diameter,…” 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 34 — Bracelet fit: measuring the usable clasp adjustment
Summary draft for “Bracelet fit: measuring the usable clasp adjustment”: the answer addresses “Record wrist circumference, removable links and the clasp…”; the related point is “Request the closed bracelet circumference rather than inferring…”. 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 6 — Maintenance question: how do I tell if an automatic actually needs service?
Sealing and movement performance are separate questions. Ask a qualified watchmaker about inspection and testing appropriate to the particular watch and its intended use; a healthy rate does not establish water resistance.
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.
Case 41 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Summary draft for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: the answer addresses “Sapphire is very hard to scratch but can chip or crack…”; the related point is “Acrylic scratches easily but flexes, rarely shatters, and light scratches…”. 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.
