Case 25 — First QC request: the minimum useful information
Clarification for “First QC request: the minimum useful information”: the point beginning “State the model configuration, the specific concern 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.
Case 27 — A maintenance log that remains useful after a sale
Keep the date, work performed, provider invoice reference and test results where available. Redact addresses and payment information; do not invent service events to fill an empty history.
Case 27 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The lift angle must match the movement specification for the amplitude reading to be meaningful. If it is unknown, label amplitude as provisional instead of accepting the instrument default.
Case 6 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Add lug-to-lug, thickness and lug width as separate rows. Diameter alone tells you little about wearability. Two cases 2mm apart in diameter can be within 1mm of each other lug to lug, and that number decides whether the watch overhangs a small wrist. Also give the source for each figure: manufacturer sheet, caliper measurement, or catalogue listing.
Case 30 — Crown operation: when a forum cannot diagnose the resistance
Method note for “Crown operation: when a forum cannot diagnose the resistance”: use “Describe whether resistance occurs during winding or setting 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.
Use fields for order date, promised terms, dated communications, delivery evidence and resolution. Leave unsupported fields blank and separate observations from opinions; this reference is not a seller endorsement.
Method note for “Forum comparison archive: link the evidence and the correction”: use “Add a dated correction near the original conclusion…” 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.
Correction note for “Magnetism and rate: record evidence before naming a cause”: retain the wording beginning “A competent watchmaker can test and diagnose it; random adjustment…” 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.
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.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “Compare multiple controlled angles and describe the visible observation without asserting…” 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 44 — A maintenance log that remains useful after a sale · source wording exercise
Correction note for “A maintenance log that remains useful after a sale”: retain the wording beginning “Redact addresses and payment information; do not invent service…” 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.
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.
Case 28 — Date window centring: compare the same date at the same angle
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” 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 8 — 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.
Case 42 — Strap compatibility: width is only the first measurement · source wording exercise
Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Avoid forcing an assembly that does not fit and…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-10924/42: address this question within its stated limits.
