Case 21 — What a water-resistance claim does and does not establish
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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. Keep the stated question separate from any broader claim.
