Case 17 — Movement identification: the limits of a rotor photograph
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Exercise RWF-29162/17: address this question within its stated limits.
Case 6 — Bracelet fit: measuring the usable clasp adjustment
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.
Limit of the answer in “Forum comparison archive: link the evidence and the correction”: “Add a dated correction near the original conclusion…” 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 31 — Case finishing: distinguish a reflection from a surface mark
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 19 — 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-24827/19: address this question within its stated limits.
Case 32 — 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 11 — What a water-resistance claim does and does not establish
Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.
Case 45 — Service enquiry: information a watchmaker can use · source wording exercise
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Be honest about the watch and request an assessment…” 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 12 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
A correction to a common assumption: a slightly loose fit isn't automatically wrong. Heavier heads tend to slide on loose bracelets, but a lighter watch often wears comfortably with a finger's width of space. Try 'loose' for a full day before deciding it doesn't work. Comfort over hours tells you more than the first minute.
Case 32 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Exercise RWF-18849/32: address this question within its stated limits.
Case 22 — Forum comparison archive: link the evidence and the correction
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.
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.
Case 22 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Use a correction row with date, old value, revised value and evidence. A worked example could change a lug-width entry from 20 to 22 mm; do not present that example as a correction to a real model.
Method note for “Comparing versions without mixing case sizes”: use “List confirmed differences separately from seller descriptions and date the comparison…” 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 14 — 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.
