Is the iPhone 7 watch waterproof?
Apple Watch Series 7, Apple Watch SE, and Apple Watch Series 3 have a water resistance rating of 50 meters under ISO standard 22810:2010. This means that they may be used for shallow-water activities like swimming in a pool or ocean. What happens if I don’t turn on Water Lock before swimming? Nothing major—your Apple Watch is still water-resistant. However: Water droplets may trigger random screen taps while you swim.
