Apple Reveals New 'Apple Watch Series 3' Models With LTE and Faster Dual-Core Processor

Apple today at the Steve Jobs Theater announced a new generation of Apple Watch called Apple Watch Series 3.

Apple Watch Series 3 is available with cellular capabilities built right into the device, so you can leave your iPhone behind and still send or receive calls and messages, listen to Apple Music, and more over LTE or 3G. Apple Watch shares the same phone number as your iPhone, but it requires an add-on plan.

Apple Watch Series 3 is also available in a Wi-Fi + GPS version without cellular. All models feature a 70 percent faster dual-core processor, a new Apple W2 chip, and a barometric altimeter.

Series 3 models look the same as Series 2 models, with 38mm and 42mm sizes in gold, silver or space gray aluminum, or silver or space black stainless steel.

Apple Watch Series 3 pre-orders start on Friday, September 15, with in-store availability beginning September 22, in the United States, Australia, Canada, China, France, Germany, Japan, Puerto Rico, Switzerland, and the United Kingdom.

Wi-Fi + GPS models start at $329, while Wi-Fi + GPS + Cellular models start at $399.

In addition, watchOS 4 includes a Heart Rate complication, and the smart watch can measure new heart rate data like resting heart rate. The Apple Watch will also notify you when it detects an elevated heart rate, and can even detect irregular heart beat rhythm thanks to the new "Apple Heart Study." watchOS 4 debuts September 19.
