Case 32 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Exercise RWF-29865/32: address this question within its stated limits.
Case 34 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Clarifying question: how are you charging it? A few seconds under a warm indoor bulb gives a much weaker charge than daylight or a UV source. Many 'weak lume' reports turn out to be undercharging. Try a consistent charge, such as 30 seconds under a phone flashlight at a fixed distance, before judging.
Case 41 — Lume comparison: keep exposure and charging conditions consistent · source wording exercise
Method note for “Lume comparison: keep exposure and charging conditions consistent”: use “Repeat with equal light source, charging duration, elapsed time and camera…” 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. Retain the source wording beside any paraphrase.
Case 32 — Reading a timegrapher recording without losing the context
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 223 — Case finishing: distinguish a reflection from a surface mark · indexing exercise
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
Review focus: indexing. Make the reasoning findable without reducing it to a trust score. Use the original answer fragment “Ask for photographs with the light moved and…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25905/223: address this question within its stated limits.
Case 9 — Case finishing: distinguish a reflection from a surface mark
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
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.
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.
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.
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 25 — 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 27 — Packing photographs: document condition without exposing an address
A condition record is useful but a shipping label contains personal information. How can the record be shared safely?
Exercise RWF-16063/27: address this question within its stated limits.
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.
Case 32 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Wrist size changes during the day and with temperature, sometimes by several millimetres. A fit that feels tight in the afternoon may be right in the morning. Before buying parts, check the fit at different times. You may find the 'too tight' setting is only a problem a few hours a day.
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
