Case 8 — 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.
Check whether a compatible half-link exists for the exact bracelet reference. Compatibility involves the connection and hardware, not just width. Ask a watchmaker if the correct part is uncertain.
One method that often helps without any service is using overnight resting position to cancel daily drift. Many watches gain in some positions and lose in others. If yours loses on the wrist, try leaving it crown up or dial up overnight and log the result for a few nights. Some people get close to zero this way.
Case 14 — 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.
Case 20 — Comparing dial colour under different lighting
Correction note for “Comparing dial colour under different lighting”: retain the wording beginning “State the lighting 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 10 — Magnetism and rate: record evidence before naming a cause
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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.
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Request a level straight-on image with the hands…” 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.
Limit of the answer in “Crown operation: when a forum cannot diagnose the resistance”: “Describe whether resistance occurs during winding or setting and…” 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.
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Case 53 — Case finishing: distinguish a reflection from a surface mark · source wording exercise
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A mark should be assessed across multiple views; aggressive polishing…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-23699/53: address this question within its stated limits.
Case 8 — 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-22187/8: address this question within its stated limits.
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.
Case 14 — Lug-to-lug and end-link overhang in wrist photographs
Record lug-to-lug and the effective span including rigid end links. Use a similar camera distance and neutral wrist position; photographs support fit discussion but do not replace measurements.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
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.
