Case 27 — Disputed observation: is this dial colour shift real or just lighting?
Clarifying question: does anyone in the thread have access to both versions at once? Without simultaneous comparison, every claim either way is weak evidence. If not, the next best option is photos with a grey card in frame and white balance locked or set manually, which at least makes separate photos roughly comparable.
Case 16 — Crystal reflections: why a dark patch is not a coating test
Correction note for “Crystal reflections: why a dark patch is not a coating test”: retain the wording beginning “No single lighting setup settles…” 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 207 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic? · correction exercise
Clarification for “Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?”: the point beginning “An example such as -8 seconds per day cannot be declared…” 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: correction. Preserve the old wording if a later source changes the interpretation.
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 20 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Log the rate over several comparable days, identify the correct specification and state the conditions. Stable and changing patterns raise different questions; a watchmaker can assess whether regulation, inspection or no action is appropriate.
Case 24 — What a water-resistance claim does and does not establish
Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.
Case 42 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
Correction note for “QC photographs: perspective or a genuinely tilted index?”: retain the wording beginning “Compare two independently aligned images before drawing a conclusion; an overlay…” 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.
Method note for “Clasp photographs: what to request before judging alignment”: use “Request open and closed views from both sides,…” 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 29 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Exercise RWF-18708/29: address this question within its stated limits.
Case 9 — Comparing dial colour under different lighting
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 11 — What a water-resistance claim does and does not establish
A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?
Exercise RWF-16063/11: address this question within its stated limits.
Case 31 — Crystal reflections: why a dark patch is not a coating test
A dark area appears at an oblique angle in a single photograph. Does that establish a coating difference?
Exercise RWF-13684/31: address this question within its stated limits.
Case 16 — Crown operation: when a forum cannot diagnose the resistance
Method note for “Crown operation: when a forum cannot diagnose the resistance”: use “Describe whether resistance occurs during winding or setting 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.
Request open and closed views from both sides, with the watch supported safely. Separate cosmetic alignment from whether the clasp engages reliably; functional concerns need hands-on inspection.
Case 25 — Lume comparison: keep exposure and charging conditions consistent
Correction note for “Lume comparison: keep exposure and charging conditions consistent”: retain the wording beginning “Treat the comparison…” 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.
