Case 40 — What a water-resistance claim does and does not establish · source wording exercise

Correction note for “What a water-resistance claim does and does not establish”: retain the wording beginning “A photograph or a caseback engraving is not…” 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.
