A new Apple Watch will launch alongside the iPhone 14 tomorrow - at least that's the common expectation.

In fact, it is thought that we'll get an Apple Watch Series 8 - a minor upgrade on the Series 7 - and an all-new Apple Watch Pro.

We've previously learned that the latter will be a better spec'ed, more sturdy model with a larger display. Now, we have some CAD renders based on reports by "industry sources" that show us the new design.

The come courtesy of 91Mobiles and show a chunkier Watch. It has that larger display, which is thought to sport a 2-inch screen, and a couple of interesting additions.

First up is a protrusion on the right-hand side, housing the digital crown. But more interesting is a button on the left-hand side of the Watch.

It's unclear what that will be used for at present, although Bloomberg's resident Apple expert, Mark Gurman, has an idea. In a Twitter posting, he suggested it could be programmable and perform any task the wearer assigns. That makes sense, as we've often found that repeatedly having to navigate to a certain app or function is unnecessarily fiddly.

We'll find out for sure tomorrow, when Apple announces all of its new products. You can join us to watch the entire event live.
