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.

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 33 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Add lug-to-lug, thickness and lug width as separate rows. Diameter alone tells you little about wearability. Two cases 2mm apart in diameter can be within 1mm of each other lug to lug, and that number decides whether the watch overhangs a small wrist. Also give the source for each figure: manufacturer sheet, caliper measurement, or catalogue listing.
Clarification for “Crown operation: when a forum cannot diagnose the resistance”: the point beginning “Describe whether resistance occurs during winding or setting and…” 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.
Limit of the answer in “Clasp photographs: what to request before judging alignment”: “Request open and closed views from both sides,…” 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 “Reading a timegrapher recording without losing the context”: the point beginning “Keep the complete recording and ask for the…” 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.
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.
Power reserve is how long the watch runs from full wind until it stops. It matters if you rotate watches: a 38-hour reserve may stop over a weekend off the wrist, while 70-plus hours may not. One clarifying point is that rate stability often gets worse near the end of the reserve, so the full figure is not all precision-grade running time.
Case 36 — QC photography: what photos actually help verify a pre-owned listing?
Clarifying question for the thread: is the goal to check authenticity, condition, or both? For condition, the request list above is enough. For authenticity, you also need caseback, serial or reference engravings, and ideally movement photos. Movement photos usually require opening the watch, which a seller may reasonably refuse without a watchmaker present.
Case 41 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
Summary draft for “Crystal reflections: why a dark patch is not a coating test”: the answer addresses “Compare multiple controlled angles and describe the visible observation without asserting…”; the related point is “No single lighting setup settles…”. 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.
Clarification for “Seller review template: facts, dates and unresolved questions”: the point beginning “Use fields for order date, promised terms, dated…” 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 46 — Clasp photographs: what to request before judging alignment · source wording exercise
Correction note for “Clasp photographs: what to request before judging alignment”: retain the wording beginning “Separate cosmetic alignment from whether the clasp engages reliably;…” 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 “Comparing versions without mixing case sizes”: use “Match reference, dimensions 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 40 — Lug-to-lug and end-link overhang in wrist photographs · source wording exercise
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: source wording. Retain the source wording beside any paraphrase.
Case 27 — Magnetism and rate: record evidence before naming a cause
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.
