Case 31 — Crystal reflections: why a dark patch is not a coating test
Method note for “Crystal reflections: why a dark patch is not a coating test”: use “No single lighting setup settles…” 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 104 — QC photographs: perspective or a genuinely tilted index? · comparison exercise
Reader check for “QC photographs: perspective or a genuinely tilted index?”: distinguish the discussion point “Request a level straight-on image with the hands…” 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: comparison. Make the basis of a comparison explicit before interpreting it.
Case 3 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
Method note for “Shipping timeline: separate dispatch, handover and scan events”: use “Distinguish label creation from physical acceptance and retain dated…” 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 “Case finishing: distinguish a reflection from a surface mark”: the point beginning “Ask for photographs with the light moved 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 20 — 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 21 — Lug-to-lug and end-link overhang in wrist photographs
Correction note for “Lug-to-lug and end-link overhang in wrist photographs”: retain the wording beginning “Record lug-to-lug and the effective span…” 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 19 — 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.
Batch variation on coloured dials does happen in general. Plating, lacquer thickness and supplier changes can all shift tone, so the claim isn't implausible. Plausible isn't the same as confirmed, though. The thread should keep 'possible' and 'shown' as separate statuses rather than letting repetition turn a hypothesis into accepted fact.
Case 46 — A maintenance log that remains useful after a sale · source wording exercise
Reader check for “A maintenance log that remains useful after a sale”: distinguish the discussion point “Redact addresses and payment information; do not invent service…” 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: source wording. Retain the source wording beside any paraphrase.
Case 6 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
Power reserve is how long the watch runs from full wind until it stops. It matters if you rotate watches: a 38-hour reserve may stop over a weekend off the wrist, while 70-plus hours may not. One clarifying point is that rate stability often gets worse near the end of the reserve, so the full figure is not all precision-grade running time.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “Compare multiple controlled angles and describe the visible observation without asserting…” 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.
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.
One method that often helps without any service is using overnight resting position to cancel daily drift. Many watches gain in some positions and lose in others. If yours loses on the wrist, try leaving it crown up or dial up overnight and log the result for a few nights. Some people get close to zero this way.
Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.
