Case 9 — QC checklist: prioritise observable faults over pixel hunting
Correction note for “QC checklist: prioritise observable faults over pixel hunting”: retain the wording beginning “Start with function, legibility, assembly 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.
Case 72 — Reading a timegrapher recording without losing the context · source wording exercise
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “A single number cannot establish service condition, movement identity…” 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.
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.
Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.
Case 7 — 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-22448/7: address this question within its stated limits.
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 24 — A maintenance log that remains useful after a sale
Summary draft for “A maintenance log that remains useful after a sale”: the answer addresses “Keep the date, work performed, provider invoice reference…”; the related point is “Redact addresses and payment information; do not invent service…”. 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 10 — Strap compatibility: width is only the first measurement
Summary draft for “Strap compatibility: width is only the first measurement”: the answer addresses “Measure the lug opening and document bar diameter,…”; the related point is “Avoid forcing an assembly that does not fit and…”. 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 15 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Exercise RWF-17881/15: address this question within its stated limits.
Case 25 — 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.
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.
Case 2 — A maintenance log that remains useful after a sale
Which information should a transferable maintenance log retain while protecting the owner’s identity?
Exercise RWF-14395/2: address this question within its stated limits.
Clarification for “Disputed observation: is this dial colour shift real or just lighting?”: the point beginning “The difficulty is that phone cameras adjust white balance automatically,…” 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 39 — Forum comparison archive: link the evidence and the correction · source wording exercise
Clarification for “Forum comparison archive: link the evidence and the correction”: the point beginning “Preserve the reasoning trail instead of silently replacing an…” 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.
Method note for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: use “Without those fields, the rate, amplitude and beat-error values lack…” 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.
