Case 38 — What a water-resistance claim does and does not establish · source wording exercise

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