Method note for “Magnetism and rate: record evidence before naming a cause”: use “Record the change and the circumstances without treating…” 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. Retain the source wording beside any paraphrase.

Add lug-to-lug, thickness and lug width as separate rows. Diameter alone tells you little about wearability. Two cases 2mm apart in diameter can be within 1mm of each other lug to lug, and that number decides whether the watch overhangs a small wrist. Also give the source for each figure: manufacturer sheet, caliper measurement, or catalogue listing.
Case 28 — Crown operation: when a forum cannot diagnose the resistance
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Exercise RWF-30203/28: address this question within its stated limits.
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.
Limit of the answer in “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: “First identify the caliber, lift-angle setting, winding…” 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 45 — Magnetism and rate: record evidence before naming a cause · source wording exercise
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A competent watchmaker can test and diagnose it; random adjustment…” as the discussion anchor; no new event or result is supplied.

Case 11 — Seller review template: facts, dates and unresolved questions
Limit of the answer in “Seller review template: facts, dates and unresolved questions”: “Use fields for order date, promised terms, dated…” 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 20 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Differences in pigment, applied area, thickness and colour can affect appearance. Keep those design differences separate from claims about quality and use matched conditions for any comparison.
Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.
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 30 — 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.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Reader check for “QC checklist: prioritise observable faults over pixel hunting”: distinguish the discussion point “Explain what the full-size image shows, what the crop adds and…” 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: scope. Keep the stated question separate from any broader claim.
Case 12 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
I want to buy aftermarket straps but keep seeing 20/16, 22mm, 4mm thick and spring bar sizes. Which measurements do I actually need to take from my watch, and how do I measure them without the right tools?
Exercise RWF-14684/12: address this question within its stated limits.
Clarification for “Disputed observation: is this dial colour shift real or just lighting?”: the point beginning “The difficulty is that phone cameras adjust white balance automatically,…” 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.
