The best smartwatch
Apple Watch Series 2 adds waterproofing and GPS, and is faster than before. The lower-cost Series 1 offers similar function minus swim and GPS. Older Apple Watch owners: just update to WatchOS 3.
The Good : The new Apple Watch is faster, has a far better OS, onboard GPS, a brighter display and is waterproof to 50 meters in salt or fresh water.
The Bad : Same battery life, mostly. GPS activity causes a big hit on battery life for running. Lacks always-on display. A tad thicker and heavier. Requires an iPhone to work.
The Bottom Line: The Apple Watch returns in a made-for-sports upgrade that adds swim functions and GPS, but anyone who's not a runner or swimmer should consider the Apple Watch Series 1 instead.
