Case 32 — 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.
Correction note for “Magnetism and rate: record evidence before naming a cause”: retain the wording beginning “Record the change and the circumstances without treating…” 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.
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “A competent watchmaker can test and diagnose it; random adjustment…” 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 16 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
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 30 — 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 10 — Case finishing: distinguish a reflection from a surface mark
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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 — Seller review template: facts, dates and unresolved questions
Clarification for “Seller review template: facts, dates and unresolved questions”: the point beginning “Use fields for order date, promised terms, dated…” 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.
Method note for “Bracelet fit: measuring the usable clasp adjustment”: use “Record wrist circumference, removable links and the clasp…” 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 31 — 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.
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Document when it stops, winding behaviour, recent impacts 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 8 — Crown operation: when a forum cannot diagnose the resistance
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Exercise RWF-13339/8: address this question within its stated limits.
Case 13 — Comparing versions without mixing case sizes
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.
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Case 177 — Forum comparison archive: link the evidence and the correction · uncertainty exercise
Summary draft for “Forum comparison archive: link the evidence and the correction”: the answer addresses “Add a dated correction near the original conclusion…”; the related point is “Preserve the reasoning trail instead of silently replacing an…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: uncertainty. Leave the unresolved part visible instead of supplying a result.
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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. Retain the source wording beside any paraphrase.
