Case 27 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
On anti-reflective coatings: inner-surface AR cuts glare without wear concerns. Outer-surface AR improves legibility further but can scuff over time, and the scuffs show up as hazy patches in certain light. When comparing two watches, check which surfaces are coated. Spec sheets often just say 'AR coated' without saying where.
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.
Case 34 — Service enquiry: information a watchmaker can use
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 6 — Lume comparison: keep exposure and charging conditions consistent
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.
Method note for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: use “Diameter alone tells you little…” 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.
Caliber is the movement's model designation, like a part number. Two watches from different brands can share the same caliber family with different finishing or regulation. On a spec sheet it tells you what's inside and roughly what service parts are available. It doesn't tell you how well that particular example was adjusted.
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 40 — Reading a timegrapher recording without losing the context · source wording exercise
Reader check for “Reading a timegrapher recording without losing the context”: distinguish the discussion point “A single number cannot establish service condition, movement identity…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.
Case 19 — Seller review template: facts, dates and unresolved questions
What belongs in a useful review template when no actual purchase experience is being asserted?
Exercise RWF-21138/19: address this question within its stated limits.
Case 31 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.
Clarification for “QC checklist: prioritise observable faults over pixel hunting”: the point beginning “Start with function, legibility, assembly 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 “Shipping timeline: separate dispatch, handover and scan events”: use “Distinguish label creation from physical acceptance and retain dated…” 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.

Limit of the answer in “Movement identification: the limits of a rotor photograph”: “Describe visible bridge shapes and markings separately…” 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.
Case 29 — 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.
