Case 26 — 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 30 — 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.
Amplitude depends on the movement and measurement setup. Compare it with appropriate specifications and a qualified watchmaker’s assessment; a universal pass/fail threshold would be misleading.
Case 28 — A maintenance log that remains useful after a sale
Clarification for “A maintenance log that remains useful after a sale”: the point beginning “Keep the date, work performed, provider invoice reference…” 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 18 — Maintenance question: how do I tell if an automatic actually needs service?
A sudden rate change has several possible causes. Ask a watchmaker to test suspected magnetism rather than diagnosing it from a compass or attempting an adjustment based on forum replies.
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
A notation like 20/16 means 20mm at the lugs, tapering to 16mm at the buckle. Taper affects look and comfort more than fit. A strong taper suits smaller and dressier cases, a straight strap suits sport watches. Your buckle or clasp also has to match the narrow end, so check that if you want to reuse an existing buckle.
Case 23 — Comparing dial colour under different lighting
State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.
Case 31 — Shipping timeline: separate dispatch, handover and scan events
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Distinguish label creation from physical acceptance and retain 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.
Case 23 — Disputed observation: is this dial colour shift real or just lighting?
Batch variation on coloured dials does happen in general. Plating, lacquer thickness and supplier changes can all shift tone, so the claim isn't implausible. Plausible isn't the same as confirmed, though. The thread should keep 'possible' and 'shown' as separate statuses rather than letting repetition turn a hypothesis into accepted fact.
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “A mark should be assessed across multiple views; aggressive polishing…” 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.
Regulation is possible if you want it closer. On many movements it's a quick adjustment by a watchmaker. Can you check whether the losing rate is consistent or getting worse? A stable -8 is a good candidate for simple regulation. A growing loss points to something else, such as falling amplitude, and regulation alone won't fix that.
Reader check for “Comparing versions without mixing case sizes”: distinguish the discussion point “Match reference, dimensions and…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.
Add a dated correction near the original conclusion and link the new evidence. Preserve the reasoning trail instead of silently replacing an uncertain claim with a confident one.
Limit of the answer in “Disputed observation: is this dial colour shift real or just lighting?”: “Two photos of the same dial under different light can…” 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.
