A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?

Discussion record: RWI-07109.

Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.

Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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.
