About Apple Watch water resistance
If you have Apple Watch Ultra, you can wear it during recreational scuba diving up to 130 feet (40 meters) and other activities like swimming, showering, and water skiing.*
Apple Watch Series 2 and later can be used for shallow-water activities like swimming in a pool or ocean, but you shouldn’t use models other than Apple Watch Ultra for diving, water skiing, or other activities involving submersion below shallow depth or high-velocity water.
Apple Watch Series 1 and Apple Watch (1st generation) are splash and water resistant, but submerging these models isn’t recommended.
Not all Apple Watch bands are appropriate for water use. For example, the stainless steel and leather bands aren’t water resistant and shouldn’t be exposed to liquids.
