Case 28 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The lift angle must match the movement specification for the amplitude reading to be meaningful. If it is unknown, label amplitude as provisional instead of accepting the instrument default.
Case 30 — Forum comparison archive: link the evidence and the correction
Limit of the answer in “Forum comparison archive: link the evidence and the correction”: “Add a dated correction near the original conclusion…” 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 31 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
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.
Case 9 — QC photography: what photos actually help verify a pre-owned listing?
A caution: photos can't settle everything. Water resistance, timekeeping and internal condition aren't visible in any image. A short timegrapher video or a stated recent rate test adds information, but treat it as a seller claim unless an independent party confirms it. Photos narrow the risk. They don't remove it.
Case 34 — Clasp photographs: what to request before judging alignment
The available image hides the hinge and only shows the outer surface. Which additional views would answer the question?
Exercise RWF-23073/34: address this question within its stated limits.
Record the change and the circumstances without treating the suspected cause as established. A competent watchmaker can test and diagnose it; random adjustment is not a substitute for assessment.
The difficulty is that phone cameras adjust white balance automatically, and blue dials are especially sensitive. Two photos of the same dial under different light can easily look like a 'batch difference'. Any comparison needs both dials in the same frame, under the same light, ideally next to a neutral grey or white reference card.
Amplitude depends on the movement and measurement setup. Compare it with appropriate specifications and a qualified watchmaker’s assessment; a universal pass/fail threshold would be misleading.
Clarification for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: the point beginning “Add lug-to-lug, thickness and lug width…” 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 48 — First QC request: the minimum useful information · source wording exercise
Clarification for “First QC request: the minimum useful information”: the point beginning “Include complete instrument settings where relevant and say…” 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.
Method note for “Comparing dial colour under different lighting”: use “State the lighting 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 32 — Lug-to-lug and end-link overhang in wrist photographs
A wide-angle wrist photo exaggerates the nearest edge of the case. How can two watches be compared fairly?
Exercise RWF-13525/32: address this question within its stated limits.
Case 12 — Seller review template: facts, dates and unresolved questions
Use fields for order date, promised terms, dated communications, delivery evidence and resolution. Leave unsupported fields blank and separate observations from opinions; this reference is not a seller endorsement.
Case 45 — Seller review template: facts, dates and unresolved questions · source wording exercise
Correction note for “Seller review template: facts, dates and unresolved questions”: retain the wording beginning “Leave unsupported fields blank and separate observations from opinions; this…” 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 20 — Bracelet fit: measuring the usable clasp adjustment
Summary draft for “Bracelet fit: measuring the usable clasp adjustment”: the answer addresses “Record wrist circumference, removable links and the clasp…”; the related point is “Request the closed bracelet circumference rather than inferring…”. 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.
