Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.

Case 240 — Disputed observation: is this dial colour shift real or just lighting? · indexing exercise
Summary draft for “Disputed observation: is this dial colour shift real or just lighting?”: the answer addresses “Batch variation on coloured dials does…”; the related point is “Plating, lacquer thickness and supplier changes can all shift…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: indexing. Make the reasoning findable without reducing it to a trust score.
Case 26 — Disputed observation: is this dial colour shift real or just lighting?
Status for now: unresolved. The claim is plausible, but no controlled comparison has been posted. Until one appears, describe it as 'reported, not verified'. When someone posts a same-frame, grey-card comparison under two lighting conditions, the thread can update the status with a date and a link to that post.
Reader check for “Shipping timeline: separate dispatch, handover and scan events”: distinguish the discussion point “Distinguish label creation from physical acceptance and retain dated…” 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 — Clasp photographs: what to request before judging alignment
Summary draft for “Clasp photographs: what to request before judging alignment”: the answer addresses “Request open and closed views from both sides,…”; the related point is “Separate cosmetic alignment from whether the clasp engages reliably;…”. 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.
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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 4 — 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.
Request a level straight-on image with the hands clear of the marker. Compare two independently aligned images before drawing a conclusion; an overlay cannot correct an oblique camera angle.
Case 43 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Ask the sender or carrier for clarification; missing scans alone…” 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 44 — Reading a timegrapher recording without losing the context · source wording exercise
Summary draft for “Reading a timegrapher recording without losing the context”: the answer addresses “A single number cannot establish service condition, movement identity…”; the related point is “Keep the complete recording and ask for the…”. 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 14 — 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 4 — Movement identification: the limits of a rotor photograph
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 50 — Seller review template: facts, dates and unresolved questions · source wording exercise
Clarification for “Seller review template: facts, dates and unresolved questions”: the point beginning “Leave unsupported fields blank and separate observations from opinions; this…” 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 14 — Model comparison: dive bezel action and alignment, how to compare fairly
Correction to earlier posts in similar threads: 120-click bezels aren't automatically worse. More positions means smaller steps, which can feel less pronounced. Comparing a 60-click and a 120-click bezel on crispness alone is apples to oranges. Compare same-click-count designs, or note the difference clearly.
No single lighting setup settles that question. Compare multiple controlled angles and describe the visible observation without asserting material specifications that have not been verified.
