Case 20 — Maintenance question: how do I tell if an automatic actually needs service?
Keep a baseline log, describe changes in rate or running time and stop forcing rough winding. Follow the manufacturer’s guidance and arrange professional assessment when operation changes. A forum cannot prescribe a universal service interval.
Case 29 — 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 20 — Maintenance question: how do I tell if an automatic actually needs service?
A sudden rate change has several possible causes. Ask a watchmaker to test suspected magnetism rather than diagnosing it from a compass or attempting an adjustment based on forum replies.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “No single lighting setup settles…” 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.
Reader check for “What a water-resistance claim does and does not establish”: distinguish the discussion point “A photograph or a caseback engraving is not…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.

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 22 — A maintenance log that remains useful after a sale
Method note for “A maintenance log that remains useful after a sale”: use “Keep the date, work performed, provider invoice reference…” 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.
A caution: photos can't settle everything. Water resistance, timekeeping and internal condition aren't visible in any image. A short timegrapher video or a stated recent rate test adds information, but treat it as a seller claim unless an independent party confirms it. Photos narrow the risk. They don't remove it.
Case 12 — Comparing versions without mixing case sizes
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “Match reference, dimensions and…”; the related point is “List confirmed differences separately from seller descriptions and date the comparison…”. 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 28 — Crystal reflections: why a dark patch is not a coating test
Limit of the answer in “Crystal reflections: why a dark patch is not a coating test”: “No single lighting setup settles…” 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 45 — Maintenance question: how do I tell if an automatic actually needs service? · source wording exercise
Correction note for “Maintenance question: how do I tell if an automatic actually needs service?”: retain the wording beginning “Useful signs, in rough order of seriousness: power reserve noticeably shorter…” 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.
Case 11 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Spec sheets list sapphire, mineral or acrylic crystals, and opinions in threads are very strong. For a daily-wear watch, what are the real trade-offs, and is an anti-reflective coating worth paying for?
