Case 45 — Lume comparison: keep exposure and charging conditions consistent · source wording exercise
Clarification for “Lume comparison: keep exposure and charging conditions consistent”: the point beginning “Repeat with equal light source, charging duration, elapsed time and camera…” 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.
Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.
Case 2 — Movement identification: the limits of a rotor photograph
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Describe visible bridge shapes and markings separately…”; the related point is “Ask a qualified watchmaker to inspect it if identification matters for…”. 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.
Case 32 — QC checklist: prioritise observable faults over pixel hunting
A large crop makes tiny differences look dramatic. How can a checklist remain proportionate?
Exercise RWF-28150/32: address this question within its stated limits.
Case 37 — Forum comparison archive: link the evidence and the correction · source wording exercise
Summary draft for “Forum comparison archive: link the evidence and the correction”: the answer addresses “Preserve the reasoning trail instead of silently replacing an…”; the related point is “Add a dated correction near the original conclusion…”. 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.
Case 79 — Case finishing: distinguish a reflection from a surface mark · comparison exercise
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved and…” 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. Make the basis of a comparison explicit before interpreting it.
Case 2 — 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.
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: scope. Keep the stated question separate from any broader claim.
Case 10 — Maintenance question: how do I tell if an automatic actually needs service?
A sudden rate change has several possible causes. Ask a watchmaker to test suspected magnetism rather than diagnosing it from a compass or attempting an adjustment based on forum replies.
Case 7 — Comparing versions without mixing case sizes
Method note for “Comparing versions without mixing case sizes”: use “Match reference, dimensions and…” 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.
Summary draft for “Seller review template: facts, dates and unresolved questions”: the answer addresses “Use fields for order date, promised terms, dated…”; the related point is “Leave unsupported fields blank and separate observations from opinions; this…”. 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.
Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.
Clarification for “Comparing versions without mixing case sizes”: the point beginning “Match reference, dimensions 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.
Method note for “Bracelet fit: measuring the usable clasp adjustment”: use “Record wrist circumference, removable links and the clasp…” 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.
