Case 21 — First QC request: the minimum useful information
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 33 — Disputed observation: is this dial colour shift real or just lighting?
The difficulty is that phone cameras adjust white balance automatically, and blue dials are especially sensitive. Two photos of the same dial under different light can easily look like a 'batch difference'. Any comparison needs both dials in the same frame, under the same light, ideally next to a neutral grey or white reference card.
Case 19 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
A useful table has columns for date, position, winding state, lift angle, rate, amplitude and beat error. Keep the full recording so settings and stability can be checked.
Case 17 — QC checklist: prioritise observable faults over pixel hunting
Summary draft for “QC checklist: prioritise observable faults over pixel hunting”: the answer addresses “Start with function, legibility, assembly and…”; the related point is “Explain what the full-size image shows, what the crop adds and…”. 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 22 — 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.
Case 11 — QC checklist: prioritise observable faults over pixel hunting
Correction note for “QC checklist: prioritise observable faults over pixel hunting”: retain the wording beginning “Start with function, legibility, assembly 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 202 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem · correction exercise
Clarification for “Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem”: the point beginning “Wrist size changes during the day and with…” 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: correction. Preserve the old wording if a later source changes the interpretation.
Method note for “A maintenance log that remains useful after a sale”: use “Redact addresses and payment information; do not invent service…” 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 15 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Resolution checklist. 1) Rebalance links around the clasp. 2) Test every micro-adjust hole with each link count. 3) Check fit morning and afternoon. 4) Look for half-links by bracelet reference. 5) Accept slightly loose if the head is light. If none of that works, a strap with finer hole spacing is a reasonable conclusion, not a failure.
Case 19 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
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 37 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise
Correction note for “Disputed observation: is this dial colour shift real or just lighting?”: retain the wording beginning “Two photos of the same dial under different light can…” 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. Retain the source wording beside any paraphrase.
Case 24 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
My entry-level automatic loses about 8 seconds a day. The spec sheet lists a tolerance range, but I'm not sure how to read it or whether my measurement is reliable. Is this something to fix or something to live with?
Exercise RWF-18708/24: address this question within its stated limits.
Case 4 — Lug-to-lug and end-link overhang in wrist photographs
Method note for “Lug-to-lug and end-link overhang in wrist photographs”: use “Record lug-to-lug and the effective span…” 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 6 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Spec sheets list sapphire, mineral or acrylic crystals, and opinions in threads are very strong. For a daily-wear watch, what are the real trade-offs, and is an anti-reflective coating worth paying for?
Exercise RWF-16063/6: address this question within its stated limits.
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.
