Case 48 — Bracelet fit: measuring the usable clasp adjustment · source wording exercise
Clarification for “Bracelet fit: measuring the usable clasp adjustment”: the point beginning “Request the closed bracelet circumference rather than inferring…” 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 177 — What a water-resistance claim does and does not establish · uncertainty exercise
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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: uncertainty. Leave the unresolved part visible instead of supplying a result.
Case 49 — Service enquiry: information a watchmaker can use · source wording exercise
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Be honest about the watch and request an assessment…” 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.
Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.
Case 12 — Service enquiry: information a watchmaker can use
Limit of the answer in “Service enquiry: information a watchmaker can use”: “Document when it stops, winding behaviour, recent impacts 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.
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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 28 — 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.

Case 37 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
Correction note for “QC checklist: prioritise observable faults over pixel hunting”: retain the wording beginning “Explain what the full-size image shows, what the crop adds 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. Retain the source wording beside any paraphrase.
Limit of the answer in “Comparing dial colour under different lighting”: “State the lighting 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.
Case 1 — QC photography: what photos actually help verify a pre-owned listing?
When asking a seller for extra photos of a pre-owned watch, what shots are actually useful as evidence? Listings tend to have glossy angled photos that hide more than they show. I'd like a standard request list the forum can reuse.
Exercise RWF-13684/1: address this question within its stated limits.
Limit of the answer in “Strap compatibility: width is only the first measurement”: “Measure the lug opening and document bar diameter,…” 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: source wording. Retain the source wording beside any paraphrase.
A bright initial glow followed by a steep drop is normal for photoluminescent pigments. Afterglow fades fastest in the first minutes and then settles to a dim, long-lasting level that dark-adapted eyes can still read. The real question is whether it's readable after an hour in darkness, not how it looks right after charging.
Describe whether resistance occurs during winding or setting and whether the crown engages consistently. Stop forcing it and arrange inspection rather than trying an unverified repair from a thread.
Case 16 — 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 4 — 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.
