Apple Watch Series 4 has a water resistance rating of 50 meters under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch Series 4 should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth.
Apple Watch Series 4 inspires you to live a healthier life by helping you manage everything from everyday stress to calories burned. At the same time, it monitors your heart rate and lets you know if it detects something of concern. And that sense of security now goes a step further with fall detection and Emergency SOS. The new Apple Watch has your back — as well as your heart.
