Case 6 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Log the rate over several comparable days, identify the correct specification and state the conditions. Stable and changing patterns raise different questions; a watchmaker can assess whether regulation, inspection or no action is appropriate.
Case 6 — 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 9 — Maintenance question: how do I tell if an automatic actually needs service?
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
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 44 — Magnetism and rate: record evidence before naming a cause · source wording exercise
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “A competent watchmaker can test and diagnose it; random adjustment…” 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 24 — 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-19469/24: address this question within its stated limits.
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 48 — Reading a timegrapher recording without losing the context · source wording exercise
Summary draft for “Reading a timegrapher recording without losing the context”: the answer addresses “A single number cannot establish service condition, movement identity…”; the related point is “Keep the complete recording and ask for the…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
Case 23 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.
Case 7 — Magnetism and rate: record evidence before naming a cause
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 20 — Forum comparison archive: link the evidence and the correction
Correction note for “Forum comparison archive: link the evidence and the correction”: retain the wording beginning “Add a dated correction near the original conclusion…” 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 “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.
First identify the caliber, lift-angle setting, winding state and measurement position. Without those fields, the rate, amplitude and beat-error values lack enough context for a useful comparison.
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.
Limit of the answer in “Lume comparison: keep exposure and charging conditions consistent”: “Treat the comparison…” 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.
