Case 38 — What a water-resistance claim does and does not establish · source wording exercise
Correction note for “What a water-resistance claim does and does not establish”: retain the wording beginning “A photograph or a caseback engraving is not…” 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.
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Document when it stops, winding behaviour, recent impacts and…” 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 31 — What a water-resistance claim does and does not establish
A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?
Exercise RWF-27959/31: address this question within its stated limits.
Ask for a straight-on dial photo with diffuse light and no flash, the full dial in frame, and the hands placed away from the indices (10:10 isn't ideal, because it covers the upper markers). Flash flattens printing and hides lume condition. Diffuse light shows print edges, alignment and any spotting.
Case 4 — Clasp photographs: what to request before judging alignment
Method note for “Clasp photographs: what to request before judging alignment”: use “Request open and closed views from both sides,…” 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.
Clarification for “Strap compatibility: width is only the first measurement”: the point beginning “Measure the lug opening and document bar diameter,…” 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.
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.
Case 14 — A maintenance log that remains useful after a sale
Keep the date, work performed, provider invoice reference and test results where available. Redact addresses and payment information; do not invent service events to fill an empty history.
Use fields for order date, promised terms, dated communications, delivery evidence and resolution. Leave unsupported fields blank and separate observations from opinions; this reference is not a seller endorsement.
Correction note for “Reading a timegrapher recording without losing the context”: retain the wording beginning “Keep the complete recording and ask for the…” 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.
Case 41 — Lume questions: why does my lume fade so quickly, and how should I compare it? · source wording exercise
Correction note for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: retain the wording beginning “Afterglow fades fastest in the first minutes and then settles to…” 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.
Case 48 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me? · source wording exercise
Clarification for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: the point beginning “Without those fields, the rate, amplitude and beat-error values lack…” 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.
Clarification for “Movement identification: the limits of a rotor photograph”: the point beginning “Describe visible bridge shapes and markings separately…” 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.
Ask for a straight-on dial photo with diffuse light and no flash, the full dial in frame, and the hands placed away from the indices (10:10 isn't ideal, because it covers the upper markers). Flash flattens printing and hides lume condition. Diffuse light shows print edges, alignment and any spotting.
Measure the lug opening and document bar diameter, shoulder position and strap thickness. Avoid forcing an assembly that does not fit and let a watchmaker check uncertain clearances.
