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 6 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
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.
Limit of the answer in “Date window centring: compare the same date at the same angle”: “Keep the uncropped originals alongside the detail crops and distinguish…” 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 41 — Comparing versions without mixing case sizes · source wording exercise
Correction note for “Comparing versions without mixing case sizes”: retain the wording beginning “List confirmed differences separately from seller descriptions and date 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. Retain the source wording beside any paraphrase.
Case 21 — QC photographs: perspective or a genuinely tilted index?
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” 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.
Regulation is possible if you want it closer. On many movements it's a quick adjustment by a watchmaker. Can you check whether the losing rate is consistent or getting worse? A stable -8 is a good candidate for simple regulation. A growing loss points to something else, such as falling amplitude, and regulation alone won't fix that.
Case 46 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Clarification for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: the point beginning “Sapphire is very hard to scratch but can chip or crack…” 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.
Case 20 — Disputed observation: is this dial colour shift real or just lighting?
Something to keep apart: sunburst and gradient dials can look like different colours depending on viewing angle, even on the same piece. A shift that appears only at certain angles is a finish effect, not a batch difference. Include a straight-on shot and one tilted shot so readers can tell the two apart.
Limit of the answer in “Shipping timeline: separate dispatch, handover and scan events”: “Distinguish label creation from physical acceptance and retain 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 4 — Comparing versions without mixing case sizes
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.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Case 18 — Packing photographs: document condition without exposing an address
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
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.
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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.
