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 41 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Method note for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: use “Sapphire is very hard to scratch but can chip or crack…” 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. Retain the source wording beside any paraphrase.
Use the same numeral, camera axis and approximate image scale. Keep the uncropped originals alongside the detail crops and distinguish optical balance from physical window alignment.

Limit of the answer in “Bracelet fit: measuring the usable clasp adjustment”: “Record wrist circumference, removable links and the clasp…” 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 “Strap dimensions: lug width, taper, thickness and spring bar diameter explained”: retain the wording beginning “Lug width is the essential one: the inside distance between…” 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. Keep the stated question separate from any broader claim.
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” 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.
