One of the key new features of the Apple Watch Series 2 is an improved water resistance rating of up to 50 meters under ISO standard 22810:2010, which by definition means the watch can be used for shallow-water activities such as swimming in a pool or ocean, white water rafting, and fishing without risking water damage.
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.
