Case 12 — 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.
A complication is any function beyond hours, minutes and seconds. A date window counts, technically, and so do a chronograph, GMT hand or moon phase. More complications usually mean more parts, more thickness and more service cost. For a first everyday watch, decide which functions you'd really use before treating them as value.
Case 24 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
My bracelet is either slightly too tight or slightly loose with any link combination. The clasp has three micro-adjust holes, and there are no half-links. What are the options before I give up and go to a strap?

Case 5 — Date window centring: compare the same date at the same angle
Summary draft for “Date window centring: compare the same date at the same angle”: the answer addresses “Use the same numeral, camera axis…”; the related point is “Keep the uncropped originals alongside the detail crops and distinguish…”. 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 5 — 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 4 — Date window centring: compare the same date at the same angle
Correction note for “Date window centring: compare the same date at the same angle”: retain the wording beginning “Use the same numeral, camera axis…” 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.
A notation like 20/16 means 20mm at the lugs, tapering to 16mm at the buckle. Taper affects look and comfort more than fit. A strong taper suits smaller and dressier cases, a straight strap suits sport watches. Your buckle or clasp also has to match the narrow end, so check that if you want to reuse an existing buckle.
Case 7 — 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 42 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
Limit of the answer in “QC checklist: prioritise observable faults over pixel hunting”: “Explain what the full-size image shows, what the crop adds and…” 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: source wording. Retain the source wording beside any paraphrase.
Case 22 — Reading a timegrapher recording without losing the context
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “Keep the complete recording and ask for the…” 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.
Correction note for “Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?”: retain the wording beginning “Start with how you…” 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 47 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
A marker can look tilted when the camera is above the dial axis. What extra image would separate perspective from an assembly issue?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare two independently aligned images before drawing a conclusion; an overlay…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-17103/47: address this question within its stated limits.
Case 21 — Model comparison: dive bezel action and alignment, how to compare fairly
Separate preference from a potential functional problem. Inconsistent engagement, slipping or uncertain alignment should be documented and checked against the design’s specification by a competent watchmaker; do not invent a universal defect threshold.
Correction note for “Seller review template: facts, dates and unresolved questions”: retain the wording beginning “Use fields for order date, promised terms, dated…” 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 5 — QC checklist: prioritise observable faults over pixel hunting
Method note for “QC checklist: prioritise observable faults over pixel hunting”: use “Start with function, legibility, assembly 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.
