Case 46 — Magnetism and rate: record evidence before naming a cause · source wording exercise
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. Retain the source wording beside any paraphrase.
Case 21 — 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 8 — Movement identification: the limits of a rotor photograph
Method note for “Movement identification: the limits of a rotor photograph”: use “Describe visible bridge shapes and markings separately…” 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 6 — 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.
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.
Summary draft for “Crystal reflections: why a dark patch is not a coating test”: the answer addresses “Compare multiple controlled angles and describe the visible observation without asserting…”; the related point is “No single lighting setup settles…”. 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.
Clarification for “Forum comparison archive: link the evidence and the correction”: the point beginning “Add a dated correction near the original conclusion…” 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 36 — Maintenance question: how do I tell if an automatic actually needs service?
Common advice says service every five years, but service is expensive and some people run watches much longer. What observable signs actually indicate a mechanical watch needs attention, as opposed to just being due on a calendar?
Exercise RWF-21138/36: address this question within its stated limits.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Limit of the answer in “Lume comparison: keep exposure and charging conditions consistent”: “Repeat with equal light source, charging duration, elapsed time and camera…” 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 8 — 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 16 — Forum comparison archive: link the evidence and the correction
Clarification for “Forum comparison archive: link the evidence and the correction”: the point beginning “Add a dated correction near the original conclusion…” 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 20 — Magnetism and rate: record evidence before naming a cause
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Exercise RWF-12792/20: address this question within its stated limits.
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.
Start with function, legibility, assembly and clear visible damage. Explain what the full-size image shows, what the crop adds and what remains uncertain; do not turn an overlay into an automatic verdict.
