Apple Watch Series 3
The third generation of the Apple Watch goes beyond its predecessors -- and catches up with smartwatches from rivals such as Samsung -- with the addition of cellular connectivity. That means the smartwatch won't need proximity to an iPhone any longer, including for uses such as making phone calls and using Siri. Other changes in the third-gen Apple Watch include a new dual-core processor that offers a 70 percent improvement in performance. Plus, along with being "swim-proof" like the previous generation, the Series 3 case is not any larger than the second-gen model.
