Case 285 — What a water-resistance claim does and does not establish · reader check exercise
Method note for “What a water-resistance claim does and does not establish”: use “A photograph or a caseback engraving is not…” 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. State what a new reader can and cannot infer from this exercise.
No single lighting setup settles that question. Compare multiple controlled angles and describe the visible observation without asserting material specifications that have not been verified.
Case 28 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.
Case 10 — 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 12 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
My entry-level automatic loses about 8 seconds a day. The spec sheet lists a tolerance range, but I'm not sure how to read it or whether my measurement is reliable. Is this something to fix or something to live with?
Exercise RWF-20916/12: address this question within its stated limits.
Case 49 — Reading a timegrapher recording without losing the context · source wording exercise
Summary draft for “Reading a timegrapher recording without losing the context”: the answer addresses “A single number cannot establish service condition, movement identity…”; the related point is “Keep the complete recording and ask for the…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
Case 9 — Service enquiry: information a watchmaker can use
Correction note for “Service enquiry: information a watchmaker can use”: retain the wording beginning “Document when it stops, winding behaviour, recent impacts 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 24 — Comparing versions without mixing case sizes
Match reference, dimensions and configuration first. List confirmed differences separately from seller descriptions and date the comparison so later readers understand its scope.
Case 37 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Ask the sender or carrier for clarification; missing scans alone…” 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 49 — 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 “Date window centring: compare the same date at the same angle”: “Use the same numeral, camera axis…” 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.
Clarification for “Clasp photographs: what to request before judging alignment”: the point beginning “Request open and closed views from both sides,…” 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.
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.
Correction note for “Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem”: retain the wording beginning “First, a clarifying question: how many links are on each…” 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 34 — Lug-to-lug and end-link overhang in wrist photographs
Limit of the answer in “Lug-to-lug and end-link overhang in wrist photographs”: “Record lug-to-lug and the effective span…” 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.
