Handwashing and rain only — not for swimming. Common on dress watches. We list 16 watches rated 30m. 11 are mechanical (7 automatic, 4 hand-wound) and 5 run on a battery or light. 7 have a sapphire crystal. Cases run from 34mm to 41mm.

What 30m water resistance actually means

A 30m rating does not mean you can swim 30 metres down. Water-resistance figures come from a static pressure test (ISO 22810) — the watch is held at a pressure equivalent to that depth, motionless, in a lab. Moving your arm through water generates dynamic pressure well above the static figure, which is why 30m is rated for handwashing and rain but not swimming.

Water resistance is not permanent — gaskets compress and age. Manufacturers generally recommend a pressure re-test if the case has been opened, or periodically for a watch used in water.
