Case 38 — 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.

Case 26 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Lume photos are close to useless for comparison unless exposure is fixed. Phones raise exposure automatically in the dark, so a dim watch can look as bright as a strong one. For a fair photo comparison: same charge method, same delay after charging, manual exposure, and both watches in the same frame.
Case 26 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
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 31 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.
Case 22 — QC photography: what photos actually help verify a pre-owned listing?
When asking a seller for extra photos of a pre-owned watch, what shots are actually useful as evidence? Listings tend to have glossy angled photos that hide more than they show. I'd like a standard request list the forum can reuse.

Case 212 — Date window centring: compare the same date at the same angle · correction exercise
Correction note for “Date window centring: compare the same date at the same angle”: retain the wording beginning “Keep the uncropped originals alongside the detail crops and distinguish…” 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. Preserve the old wording if a later source changes the interpretation.
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 26 — What a water-resistance claim does and does not establish
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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 29 — Lume comparison: keep exposure and charging conditions consistent
Correction note for “Lume comparison: keep exposure and charging conditions consistent”: retain the wording beginning “Treat the comparison…” 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 48 — Service enquiry: information a watchmaker can use · source wording exercise
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Be honest about the watch and request an assessment…” 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: source wording. Retain the source wording beside any paraphrase.
Use a correction row with date, old value, revised value and evidence. A worked example could change a lug-width entry from 20 to 22 mm; do not present that example as a correction to a real model.
Case 34 — Strap compatibility: width is only the first measurement
Limit of the answer in “Strap compatibility: width is only the first measurement”: “Measure the lug opening and document bar diameter,…” 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 15 — Magnetism and rate: record evidence before naming a cause
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?

Case 16 — 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.
Method note for “Comparing dial colour under different lighting”: use “State the lighting 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.
