Case 44 — What a water-resistance claim does and does not establish · source wording exercise

Reader check for “What a water-resistance claim does and does not establish”: distinguish the discussion point “A photograph or a caseback engraving is not…” 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: source wording. Retain the source wording beside any paraphrase.
