Case 26 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
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.
Case 31 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
A correction worth making: 'sapphire = premium, mineral = cheap' oversimplifies it. A well-fitted mineral crystal on a modest watch can be perfectly suitable, and replacing a cracked sapphire is usually more expensive. Material is one factor among several, alongside fit, gasket quality and coating.
Case 21 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The reported numbers alone do not establish damage or the need for service. Confirm the setup, collect comparable readings and ask a watchmaker to assess a concerning or changing pattern.
Case 212 — Date window centring: compare the same date at the same angle · correction exercise
Limit of the answer in “Date window centring: compare the same date at the same angle”: “Keep the uncropped originals alongside the detail crops and distinguish…” 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: correction. Preserve the old wording if a later source changes the interpretation.
Case 26 — What a water-resistance claim does and does not establish
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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 29 — Lume comparison: keep exposure and charging conditions consistent
Limit of the answer in “Lume comparison: keep exposure and charging conditions consistent”: “Treat the comparison…” 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 48 — Service enquiry: information a watchmaker can use · source wording exercise
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Be honest about the watch and request an assessment…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-20816/48: address this question within its stated limits.
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
Case 34 — Strap compatibility: width is only the first measurement
Method note for “Strap compatibility: width is only the first measurement”: use “Measure the lug opening and document bar diameter,…” 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 14 — Clasp photographs: what to request before judging alignment
Summary draft for “Clasp photographs: what to request before judging alignment”: the answer addresses “Request open and closed views from both sides,…”; the related point is “Separate cosmetic alignment from whether the clasp engages reliably;…”. 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 16 — Lume comparison: keep exposure and charging conditions consistent
Method note for “Lume comparison: keep exposure and charging conditions consistent”: use “Treat the comparison…” 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 “Comparing dial colour under different lighting”: the point beginning “State the lighting 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 21 — Magnetism and rate: record evidence before naming a cause
Summary draft for “Magnetism and rate: record evidence before naming a cause”: the answer addresses “Record the change and the circumstances without treating…”; the related point is “A competent watchmaker can test and diagnose it; random adjustment…”. 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.
Correction note for “First QC request: the minimum useful information”: retain the wording beginning “State the model configuration, the specific concern 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 31 — Comparing versions without mixing case sizes
Match reference, dimensions and configuration first. List confirmed differences separately from seller descriptions and date the comparison so later readers understand its scope.
