Case 14 — 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.
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.
Case 37 — QC photography: what photos actually help verify a pre-owned listing? · source wording exercise
Correction note for “QC photography: what photos actually help verify a pre-owned listing?”: retain the wording beginning “Flash flattens printing and hides…” 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 41 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
Limit of the answer in “QC checklist: prioritise observable faults over pixel hunting”: “Explain what the full-size image shows, what the crop adds 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: source wording. Retain the source wording beside any paraphrase.
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Use a similar camera distance and neutral wrist position; photographs support…” 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 39 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained · source wording exercise
Method note for “Strap dimensions: lug width, taper, thickness and spring bar diameter explained”: use “Measure with a ruler marked in millimetres, ideally…” 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 29 — Date window centring: compare the same date at the same angle
Limit of the answer in “Date window centring: compare the same date at the same angle”: “Use the same numeral, camera axis…” 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 9 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
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.
Case 34 — First QC request: the minimum useful information
State the model configuration, the specific concern and links to clear redacted images. Include complete instrument settings where relevant and say explicitly what evidence is missing.
Case 8 — 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.
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 34 — Service enquiry: information a watchmaker can use
Method note for “Service enquiry: information a watchmaker can use”: use “Document when it stops, winding behaviour, recent impacts and…” 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.
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 6 — Strap compatibility: width is only the first measurement
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.
