Apple Watch Series 2

The second Apple Watch answered the biggest complaints about the original: running without a phone and getting wet. A built-in GPS chip tracked pace and routes on its own, while a sealed case rated to 50 metres allowed pool and open-water swims, with a speaker that could eject water.

The OLED panel became twice as bright at a peak of 1,000 nits, which made it much easier to read outdoors. The S2 dual-core processor and a larger battery kept the usual all-day endurance despite the extra hardware.

Aluminium and stainless steel versions were joined by a white ceramic model that took over from the 18-karat gold Edition. Nike+ and Hermès editions appeared as well, showing how fashion partners would shape the line.
