Case 12 — Comparing versions without mixing case sizes
Limit of the answer in “Comparing versions without mixing case sizes”: “Match reference, dimensions and…” 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.
Separate preference from a potential functional problem. Inconsistent engagement, slipping or uncertain alignment should be documented and checked against the design’s specification by a competent watchmaker; do not invent a universal defect threshold.
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.
Method note for “Movement identification: the limits of a rotor photograph”: use “Describe visible bridge shapes and markings separately…” 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 26 — 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 38 — Movement identification: the limits of a rotor photograph · source wording exercise
Method note for “Movement identification: the limits of a rotor photograph”: use “Ask a qualified watchmaker to inspect it if identification matters for…” 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.
Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.
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 6 — Comparing dial colour under different lighting
Clarification for “Comparing dial colour under different lighting”: the point beginning “State the lighting 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 36 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
Case 10 — Strap compatibility: width is only the first measurement
Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
Exercise RWF-12792/10: address this question within its stated limits.
Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.
Case 19 — Packing photographs: document condition without exposing an address
A condition record is useful but a shipping label contains personal information. How can the record be shared safely?
Exercise RWF-09267/19: address this question within its stated limits.
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.
Case 3 — Strap compatibility: width is only the first measurement
Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
