Case 10 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
A correction worth making: 'sapphire = premium, mineral = cheap' oversimplifies it. A well-fitted mineral crystal on a modest watch can be perfectly suitable, and replacing a cracked sapphire is usually more expensive. Material is one factor among several, alongside fit, gasket quality and coating.
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.
Case 28 — Strap compatibility: width is only the first measurement
Limit of the answer in “Strap compatibility: width is only the first measurement”: “Measure the lug opening and document bar diameter,…” 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 48 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Limit of the answer in “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: “Sapphire is very hard to scratch but can chip or crack…” 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: source wording. Retain the source wording beside any paraphrase.
Case 8 — Strap compatibility: width is only the first measurement
Limit of the answer in “Strap compatibility: width is only the first measurement”: “Measure the lug opening and document bar diameter,…” 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.
Correction note for “Service enquiry: information a watchmaker can use”: retain the wording beginning “Document when it stops, winding behaviour, recent impacts and…” 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 5 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
Amplitude depends on the movement and measurement setup. Compare it with appropriate specifications and a qualified watchmaker’s assessment; a universal pass/fail threshold would be misleading.
Case 20 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
My bracelet is either slightly too tight or slightly loose with any link combination. The clasp has three micro-adjust holes, and there are no half-links. What are the options before I give up and go to a strap?
Exercise RWF-18239/20: address this question within its stated limits.
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.

Case 30 — Comparing dial colour under different lighting
State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.
Case 12 — Movement identification: the limits of a rotor photograph
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Exercise RWF-13435/12: address this question within its stated limits.
Reader check for “Reading a timegrapher recording without losing the context”: distinguish the discussion point “A single number cannot establish service condition, movement identity…” 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.
Case 12 — QC photography: what photos actually help verify a pre-owned listing?
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 31 — 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.
