Case 9 — Maintenance question: how do I tell if an automatic actually needs service?
Clarifying question first: do you have a baseline? If you've never recorded the watch's rate or power reserve, 'drifting' is hard to judge. Start a simple log now with daily offset against a reference time for a week, and the hours it runs from full wind. Once you have that, later changes mean something.
Method note for “Reading a timegrapher recording without losing the context”: use “Keep the complete recording and ask for the…” 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 10 — 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 note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “Ask for photographs with the light moved 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 23 — Packing photographs: document condition without exposing an address
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Case 21 — Reading a timegrapher recording without losing the context
The supplied screen shows a rate but does not identify the lift angle, position or winding state. Which observations should accompany the recording?
Exercise RWF-19794/21: address this question within its stated limits.
Case 10 — Clasp photographs: what to request before judging alignment
The available image hides the hinge and only shows the outer surface. Which additional views would answer the question?
Exercise RWF-18849/10: address this question within its stated limits.
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 42 — Date window centring: compare the same date at the same angle · source wording exercise
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Keep the uncropped originals alongside the detail crops and distinguish…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-16139/42: address this question within its stated limits.
Summary draft for “A maintenance log that remains useful after a sale”: the answer addresses “Keep the date, work performed, provider invoice reference…”; the related point is “Redact addresses and payment information; do not invent service…”. 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.
The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.
Clarification for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: the point beginning “A bright initial glow followed by a steep drop…” 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 14 — Comparing dial colour under different lighting
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?
Exercise RWF-09192/14: address this question within its stated limits.
Case 18 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
Amplitude depends on the movement and measurement setup. Compare it with appropriate specifications and a qualified watchmaker’s assessment; a universal pass/fail threshold would be misleading.
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “A mark should be assessed across multiple views; aggressive polishing…” 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.
