• Apple Watch Series 3: What's the story so far?

It should therefore mean Apple's new Watch will be unveiled alongside the new iPhone trio: iPhone 7S, 7S Plus and iPhone 8, at Apple's event in September. Of course, there is always the possibility Apple will hold a separate event solely for the Watch Series 3.

The Apple Watch Series 3 is strongly rumoured to introduce LTE connectivity, meaning it won't need to rely on an iPhone for a data connection. It would however mean it will need its own data plan, but it's too early to speculate how much that might cost.

With regards to other specs and features for the Apple Watch Series 3, not a lot has been said. We expect it will feature built-in GPS and a waterproof body since they were introduced on the Series 2, and will also likely come with a new processor chip.

Design-wise, we're not expecting too much of a change from the current square face in 38mm and 42mm sizes, with interchangeable straps.
