Case 56 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
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: source wording. Retain the source wording beside any paraphrase.
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 30 — What a water-resistance claim does and does not establish
Limit of the answer in “What a water-resistance claim does and does not establish”: “Ask a qualified watchmaker about a suitable test for that individual…” 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 “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.
Case 52 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise
Clarification for “Disputed observation: is this dial colour shift real or just lighting?”: the point beginning “Two photos of the same dial under different light can…” 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.
Case 4 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
A correction worth making: 'sapphire = premium, mineral = cheap' oversimplifies it. A well-fitted mineral crystal on a modest watch can be perfectly suitable, and replacing a cracked sapphire is usually more expensive. Material is one factor among several, alongside fit, gasket quality and coating.
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.
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” 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 5 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
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.
Wrist size changes during the day and with temperature, sometimes by several millimetres. A fit that feels tight in the afternoon may be right in the morning. Before buying parts, check the fit at different times. You may find the 'too tight' setting is only a problem a few hours a day.
Add a dated correction near the original conclusion and link the new evidence. Preserve the reasoning trail instead of silently replacing an uncertain claim with a confident one.
Case 19 — Bracelet fit: measuring the usable clasp adjustment
A nominal case diameter says little about a bracelet that cannot be shortened enough. How should a sizing question be documented?
Exercise RWF-11733/19: address this question within its stated limits.
Case 19 — Movement identification: the limits of a rotor photograph
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
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.
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.
