Case 34 — Lume comparison: keep exposure and charging conditions consistent
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Distinguish label creation from physical acceptance and retain dated…” 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 30 — Movement identification: the limits of a rotor photograph
Limit of the answer in “Movement identification: the limits of a rotor photograph”: “Describe visible bridge shapes and markings separately…” 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 22 — 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.
Sealing and movement performance are separate questions. Ask a qualified watchmaker about inspection and testing appropriate to the particular watch and its intended use; a healthy rate does not establish water resistance.
Case 38 — Magnetism and rate: record evidence before naming a cause · source wording exercise
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “A competent watchmaker can test and diagnose it; random adjustment…” 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 28 — First QC request: the minimum useful information
Correction note for “First QC request: the minimum useful information”: retain the wording beginning “State the model configuration, the specific concern and…” 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 32 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Micro-adjust spacing varies by clasp. Measure the actual change at each setting rather than assuming a standard number of millimetres; compare the usable range with the link length.
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. Keep the stated question separate from any broader claim.
Case 15 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Thickness matters more than people expect. Straps around 4 to 5mm at the lugs can hit the case or stop the strap folding down on watches with short lugs or tight lug-to-case clearance. Do you know whether your watch has drilled lugs or a tight gap between strap and case? That tells you how much thickness is safe.
Case 2 — QC photography: what photos actually help verify a pre-owned listing?
Proposed reusable request list. 1) Straight dial, diffuse light, hands clear of markers. 2) Both case profiles. 3) Lug tops at an angle. 4) Caseback and engravings. 5) Clasp and bracelet end links. 6) Dated note in frame. Optional: timegrapher reading or movement photos. Add or change items with a reason, and I'll keep the list current.
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 41 — Reading a timegrapher recording without losing the context · source wording exercise
The supplied screen shows a rate but does not identify the lift angle, position or winding state. Which observations should accompany the recording?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A single number cannot establish service condition, movement identity…” as the discussion anchor; no new event or result is supplied.

Case 11 — A maintenance log that remains useful after a sale
Limit of the answer in “A maintenance log that remains useful after a sale”: “Keep the date, work performed, provider invoice reference…” 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 3 — Case finishing: distinguish a reflection from a surface mark
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
