Case 44 — QC checklist: prioritise observable faults over pixel hunting · source wording exercise
Clarification for “QC checklist: prioritise observable faults over pixel hunting”: the point beginning “Explain what the full-size image shows, what the crop adds 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: source wording. Retain the source wording beside any paraphrase.
A correction to a common belief: an automatic doesn't need to match a quartz watch to be healthy. Consistency matters more than the absolute figure. A watch that's reliably -8 every day is easy to live with, since you correct it once a week. One that swings from +10 to -15 is the real concern.
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 31 — Maintenance question: how do I tell if an automatic actually needs service?
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
Case 30 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Correction to a common shortcut: don't measure lug width on an existing strap. Leather and rubber straps compress or swell, and some are made slightly undersized on purpose. Always measure between the lugs themselves, with the strap removed if possible.
Limit of the answer in “Comparing dial colour under different lighting”: “Compare controlled images where available and avoid calling a…” 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.
Limit of the answer in “QC photographs: perspective or a genuinely tilted index?”: “Request a level straight-on image with the hands…” 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 12 — Case finishing: distinguish a reflection from a surface mark
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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.
Case 9 — Date window centring: compare the same date at the same angle
Use the same numeral, camera axis and approximate image scale. Keep the uncropped originals alongside the detail crops and distinguish optical balance from physical window alignment.
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 32 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The reported numbers alone do not establish damage or the need for service. Confirm the setup, collect comparable readings and ask a watchmaker to assess a concerning or changing pattern.
Case 21 — 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 40 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Method note for “Shipping timeline: separate dispatch, handover and scan events”: use “Ask the sender or carrier for clarification; missing scans alone…” 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.

Measure the lug opening and document bar diameter, shoulder position and strap thickness. Avoid forcing an assembly that does not fit and let a watchmaker check uncertain clearances.
