What is the Apple Watch Series 3?

The Apple Watch is now in its third iteration, and while it may appear that not much has changed on the surface, there have been some developments under the hood.

The big draw for the Series 3 is the option of LTE connectivity. This means greater independence from your paired iPhone, and always-on connectivity wherever you get network coverage. The best news of all is that your Apple Watch 3 will share the same phone number as your iPhone, doing away with one of the biggest grievances of previous LTE-enabled smartwatches: juggling multiple numbers.

If you’re in the UK then it’s worth noting that, right now, only EE supports LTE connectivity for the Apple Watch Series 3, and this will cost £5 in addition to your standard monthly network tariff. The feature is more widely supported by US carriers and you can expect to pay an extra $10 on top of your usual contract for a smartwatch plan.

The Watch Series 3 sees performance improvements, too. A new S3 dual-core processor runs the show with a 70% speed hike over the previous generation, and a W2 wireless chip delivers improved Wi-Fi and Bluetooth capabilities. Now, for the first time with an Apple Watch, an altimeter is included. This provides elevation data during your exercise. In addition, built-in GPS and water-resistance to 50 metres make a welcome return.
