The reliable Mark Gurman reports that Apple’s rumored Apple Watch Pro will feature a new, bigger design with a larger display, the first Apple Watch design change since 2018.

Gurman’s report is part of an Apple Q3 earnings preview published in a Bloomberg newsletter. And if the past is any guide—think back to the iPhone X—it’s likely that the Apple Watch Pro’s new design will later become standard across all Watch models.

Apple plans to release four new Apple Watch models this fall, Gurman says, a new Apple Watch SE, Apple Watch Series 8, and a high-end “Pro” Apple Watch. There are few changes coming to lower-end models. But the Pro model looks interesting.

Apple Watch Pro will feature a larger form factor than other Apple Watches, one that some users might find off-putting, he says, and a display that is about 7 percent bigger than today’s models. It will also provide more battery life, perhaps as long as two days on low-power mode, a first for Apple Watch.

The new design is not the hoped-for and oft-rumored design with flat sides, he claims, but is rather an evolution of the current shape. It will also be made of titanium and will be more rugged.

Apple is expected to launch the new Apple Watches in September alongside new iPhones, an updated HomePod, a new Apple TV, updated iPad Pro models, and other hardware products.
