Case 2 — A maintenance log that remains useful after a sale
Keep the date, work performed, provider invoice reference and test results where available. Redact addresses and payment information; do not invent service events to fill an empty history.

Limit of the answer in “Comparing versions without mixing case sizes”: “Match reference, dimensions and…” 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 2 — What a water-resistance claim does and does not establish
Correction note for “What a water-resistance claim does and does not establish”: retain the wording beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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 7 — Crown operation: when a forum cannot diagnose the resistance
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Exercise RWF-29432/7: address this question within its stated limits.

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 26 — Clasp photographs: what to request before judging alignment
Correction note for “Clasp photographs: what to request before judging alignment”: retain the wording beginning “Request open and closed views from both sides,…” 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 1 — Lug-to-lug and end-link overhang in wrist photographs

Case 8 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Use a consistent charge, fixed exposure and several elapsed-time observations. Record readability and the conditions rather than applying an unsupported universal fade-time threshold.
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Case 11 — First QC request: the minimum useful information
Method note for “First QC request: the minimum useful information”: use “State the model configuration, the specific concern 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 24 — Disputed observation: is this dial colour shift real or just lighting?
Suggested protocol. 1) Both dials in one frame. 2) Diffuse daylight, no direct sun, plus a second shot under neutral indoor light. 3) Grey card visible. 4) No filters, no editing. 5) State camera settings if known. If both shots show the same direction of difference, the claim is supported. If the difference flips between lighting conditions, it's most likely lighting.
Match reference, dimensions and configuration first. List confirmed differences separately from seller descriptions and date the comparison so later readers understand its scope.
Clarification for “Bracelet fit: measuring the usable clasp adjustment”: the point beginning “Record wrist circumference, removable links and the clasp…” 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.
