Question: what is the difference between apple watch series 2 and series 3?
Answer: Thanks to the W2 chip and improved dual processor, the Apple Watch Series 3 is up to 70% faster than the Series 2. This makes apps faster and lasts longer. The wireless connections via WiFi and Bluetooth are also faster and more stable. ... Just like Series 2, Series 3 is completely waterproof so you can use it to swim.
