Swimming and snorkeling — the everyday-rugged sweet spot. We list 33 watches rated 100m. 24 are automatic and 9 run on a battery or light. 23 have a sapphire crystal. Cases run from 37mm to 44mm.
What 100m water resistance actually means
10 bar static (ISO 22810) — the practical floor for regular water contact: swimming and snorkelling. Still a static test, so it is not a scuba rating. This is the everyday-rugged sweet spot for people who want to stop thinking about their watch around water.
