Case 20 — 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.
Case 28 — Packing photographs: document condition without exposing an address
Method note for “Packing photographs: document condition without exposing an address”: use “Photograph the item and protective packing…” 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.
Case 20 — Maintenance question: how do I tell if an automatic actually needs service?
Common advice says service every five years, but service is expensive and some people run watches much longer. What observable signs actually indicate a mechanical watch needs attention, as opposed to just being due on a calendar?
Exercise RWF-29254/20: address this question within its stated limits.
Method note for “Packing photographs: document condition without exposing an address”: use “Photograph the item and protective packing…” 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 “What a water-resistance claim does and does not establish”: the point beginning “A photograph or a caseback engraving is not…” 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.
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.
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.
Clarifying question for the thread: is the goal to check authenticity, condition, or both? For condition, the request list above is enough. For authenticity, you also need caseback, serial or reference engravings, and ideally movement photos. Movement photos usually require opening the watch, which a seller may reasonably refuse without a watchmaker present.
Case 21 — Magnetism and rate: record evidence before naming a cause
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “Record the change and the circumstances without treating…” 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.
A useful table has columns for date, position, winding state, lift angle, rate, amplitude and beat error. Keep the full recording so settings and stability can be checked.
Case 12 — Comparing versions without mixing case sizes
Two purported versions differ in case diameter and bracelet. How can the comparison avoid attributing every difference to a revision?
Exercise RWF-19961/12: address this question within its stated limits.
Case 27 — Packing photographs: document condition without exposing an address
Correction note for “Packing photographs: document condition without exposing an address”: retain the wording beginning “Photograph the item and protective packing…” 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.
Method note for “A maintenance log that remains useful after a sale”: use “Keep the date, work performed, provider invoice reference…” 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.
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” 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.
Case 44 — QC photography: what photos actually help verify a pre-owned listing? · source wording exercise
Summary draft for “QC photography: what photos actually help verify a pre-owned listing?”: the answer addresses “Flash flattens printing and hides…”; the related point is “Diffuse light shows print edges, alignment…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
