Case 30 — Maintenance question: how do I tell if an automatic actually needs service?
Sealing and movement performance are separate questions. Ask a qualified watchmaker about inspection and testing appropriate to the particular watch and its intended use; a healthy rate does not establish water resistance.
Case 15 — Forum comparison archive: link the evidence and the correction
Summary draft for “Forum comparison archive: link the evidence and the correction”: the answer addresses “Add a dated correction near the original conclusion…”; the related point is “Preserve the reasoning trail instead of silently replacing an…”. 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.
Case 13 — Comparing dial colour under different lighting
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?

Case 17 — 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?

Case 6 — Seller review template: facts, dates and unresolved questions
What belongs in a useful review template when no actual purchase experience is being asserted?

Case 196 — First QC request: the minimum useful information · correction exercise
Method note for “First QC request: the minimum useful information”: use “Include complete instrument settings where relevant and say…” 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. Preserve the old wording if a later source changes the interpretation.
Limit of the answer in “Seller review template: facts, dates and unresolved questions”: “Use fields for order date, promised terms, dated…” 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 10 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
I'm putting together a side-by-side of the 38mm and 40mm versions of a common three-hand field watch design. The aim is a reference post we can fix over time instead of repeating the same arguments. Corrections go in a dated log at the bottom. What should the table include besides case diameter, and which specs are usually misreported?
Exercise RWF-23428/10: address this question within its stated limits.
Case 13 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Micro-adjust spacing varies by clasp. Measure the actual change at each setting rather than assuming a standard number of millimetres; compare the usable range with the link length.
Case 31 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
For a two-watch comparison, the practical order is usually case dimensions first, then power reserve if you rotate, then caliber for serviceability. Jewel count comes last. Complications only matter if you'll use them. Can you say what the two candidates are, in generic terms like 'dive style vs dress style'? The priorities shift a lot between those.
Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
Case 18 — Maintenance question: how do I tell if an automatic actually needs service?
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
Case 47 — Lume comparison: keep exposure and charging conditions consistent · source wording exercise
Clarification for “Lume comparison: keep exposure and charging conditions consistent”: the point beginning “Repeat with equal light source, charging duration, elapsed time and camera…” 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.
Clarifying question first: do you have a baseline? If you've never recorded the watch's rate or power reserve, 'drifting' is hard to judge. Start a simple log now with daily offset against a reference time for a week, and the hours it runs from full wind. Once you have that, later changes mean something.
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.
