Case 43 — Movement identification: the limits of a rotor photograph · source wording exercise
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Ask a qualified watchmaker to inspect it if identification matters for…”; the related point is “Describe visible bridge shapes and markings separately…”. 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.
Case 35 — Service enquiry: information a watchmaker can use
Correction note for “Service enquiry: information a watchmaker can use”: retain the wording beginning “Document when it stops, winding behaviour, recent impacts and…” 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 40 — Date window centring: compare the same date at the same angle · source wording exercise
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Keep the uncropped originals alongside the detail crops and distinguish…” 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.
Case 48 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
Clarification for “QC checklist: prioritise observable faults over pixel hunting”: the point beginning “Explain what the full-size image shows, what the crop adds 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: source wording. Retain the source wording beside any paraphrase.
Method note for “Packing photographs: document condition without exposing an address”: use “Photograph the item and protective packing…” 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 230 — Crystal reflections: why a dark patch is not a coating test · indexing exercise
Limit of the answer in “Crystal reflections: why a dark patch is not a coating test”: “No single lighting setup settles…” 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: indexing. Make the reasoning findable without reducing it to a trust score.
Case 16 — Crystal reflections: why a dark patch is not a coating test
Limit of the answer in “Crystal reflections: why a dark patch is not a coating test”: “No single lighting setup settles…” 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 2 — Lug-to-lug and end-link overhang in wrist photographs
Limit of the answer in “Lug-to-lug and end-link overhang in wrist photographs”: “Record lug-to-lug and the effective span…” 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.
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.
Method note for “A maintenance log that remains useful after a sale”: use “Keep the date, work performed, provider invoice reference…” 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 32 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.
Case 34 — 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 4 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
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.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
Case 39 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
Reader check for “QC photographs: perspective or a genuinely tilted index?”: distinguish the discussion point “Compare two independently aligned images before drawing a conclusion; an overlay…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.
