Apple Watch Series 2 has all the features of Apple Watch Series 1, as well as some additional ones: it is rated Water Resistant 50 Metres, so you can safely swim with it. However, Apple Watch Series 2 should not be used for scuba diving, water-skiing or other activities involving high-velocity water or submersion below shallow depth. Built-in GPS provides accurate speed, pace, distance and location information, even if you don't have your iPhone with you. And the second-generation display is more than twice as bright as before, making it the brightest Apple has ever made. Apple Watch Series 2 is available in aluminium, stainless steel or ceramic cases, and runs the latest version of watchOS.
