Case 52 — First QC request: the minimum useful information · source wording exercise
Correction note for “First QC request: the minimum useful information”: retain the wording beginning “Include complete instrument settings where relevant and say…” 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. Retain the source wording beside any paraphrase.
Case 128 — Crystal reflections: why a dark patch is not a coating test · documentation exercise
A dark area appears at an oblique angle in a single photograph. Does that establish a coating difference?
Review focus: documentation. Distinguish an original record from a proposed record format. Use the original answer fragment “Compare multiple controlled angles and describe the visible observation without asserting…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-28599/128: address this question within its stated limits.
Case 32 — QC photography: what photos actually help verify a pre-owned listing?
A dated note in the frame can support a claim that photographs are recent, but it is not conclusive proof of ownership, authenticity or an honest transaction. Treat it as one limited check alongside independent verification.
Case 28 — Maintenance question: how do I tell if an automatic actually needs service?
If the manufacturer provides a suitable procedure, a running-time log can support a service enquiry. State the winding method and stop time. A shortened run does not identify the cause by itself.
Summary draft for “Lug-to-lug and end-link overhang in wrist photographs”: the answer addresses “Use a similar camera distance and neutral wrist position; photographs support…”; the related point is “Record lug-to-lug and the effective span…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.
Case 42 — Bracelet fit: measuring the usable clasp adjustment · source wording exercise
A nominal case diameter says little about a bracelet that cannot be shortened enough. How should a sizing question be documented?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Request the closed bracelet circumference rather than inferring…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-22474/42: address this question within its stated limits.
Case 47 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
A dark area appears at an oblique angle in a single photograph. Does that establish a coating difference?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare multiple controlled angles and describe the visible observation without asserting…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-21408/47: address this question within its stated limits.
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 39 — Case finishing: distinguish a reflection from a surface mark · source wording exercise
Clarification for “Case finishing: distinguish a reflection from a surface mark”: the point beginning “A mark should be assessed across multiple views; aggressive polishing…” 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.
Limit of the answer in “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: “Add lug-to-lug, thickness and lug width…” 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.
Differences in pigment, applied area, thickness and colour can affect appearance. Keep those design differences separate from claims about quality and use matched conditions for any comparison.
Case 45 — Lume questions: why does my lume fade so quickly, and how should I compare it? · source wording exercise
Clarification for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: the point beginning “Afterglow fades fastest in the first minutes and then settles to…” 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 30 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
I want to buy aftermarket straps but keep seeing 20/16, 22mm, 4mm thick and spring bar sizes. Which measurements do I actually need to take from my watch, and how do I measure them without the right tools?
Exercise RWF-13190/30: address this question within its stated limits.
First identify the caliber, lift-angle setting, winding state and measurement position. Without those fields, the rate, amplitude and beat-error values lack enough context for a useful comparison.
Case 13 — 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.
