These activities are in addition to the previous IPX7 splash resistance that allows for the Apple Watch, including first-generation models, to be worn while washing your hands or jogging in the rain. Many original Apple Watch owners also routinely shower and swim with the device, although Apple never officially recommended such activities.
However, while the Apple Watch Series 2 has improved water and dust resistance, fine print on Apple's website says the device should not be used while scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth, presumably including jet skiing and deep water snorkeling.
Apple Watch Series 2 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 2 should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth.Apple Watch Series 2 models are priced from $369 and will be available starting Friday, September 16 in the U.S. and select other launch countries.
