Case 1 — Strap compatibility: width is only the first measurement
Correction note for “Strap compatibility: width is only the first measurement”: retain the wording beginning “Measure the lug opening and document bar diameter,…” 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.
Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.
Clarifying question: does anyone in the thread have access to both versions at once? Without simultaneous comparison, every claim either way is weak evidence. If not, the next best option is photos with a grey card in frame and white balance locked or set manually, which at least makes separate photos roughly comparable.
Case 42 — Model comparison: dive bezel action and alignment, how to compare fairly · source wording exercise
Clarification for “Model comparison: dive bezel action and alignment, how to compare fairly”: the point beginning “Crisp vs mushy is mostly about…” 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 170 — Lume questions: why does my lume fade so quickly, and how should I compare it? · uncertainty exercise
Reader check for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: distinguish the discussion point “A few seconds under a warm indoor bulb gives a much…” 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: uncertainty. Leave the unresolved part visible instead of supplying a result.
Case 42 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Reader check for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: distinguish the discussion point “Sapphire is very hard to scratch but can chip or crack…” 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: source wording. Retain the source wording beside any paraphrase.
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 6 — QC photographs: perspective or a genuinely tilted index?
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.
Case 33 — Maintenance question: how do I tell if an automatic actually needs service?
If the manufacturer provides a suitable procedure, a running-time log can support a service enquiry. State the winding method and stop time. A shortened run does not identify the cause by itself.
Correction to a common shortcut: don't measure lug width on an existing strap. Leather and rubber straps compress or swell, and some are made slightly undersized on purpose. Always measure between the lugs themselves, with the strap removed if possible.
Case 21 — A maintenance log that remains useful after a sale
Correction note for “A maintenance log that remains useful after a sale”: retain the wording beginning “Keep the date, work performed, provider invoice reference…” 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 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.
Summary draft for “QC checklist: prioritise observable faults over pixel hunting”: the answer addresses “Start with function, legibility, assembly and…”; the related point is “Explain what the full-size image shows, what the crop adds 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 38 — Strap compatibility: width is only the first measurement · source wording exercise
Reader check for “Strap compatibility: width is only the first measurement”: distinguish the discussion point “Avoid forcing an assembly that does not fit 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: source wording. Retain the source wording beside any paraphrase.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
