In addition to the Apple Watch Series 8, Apple unveiled a brand new Apple Watch model at its press conference. The Apple Watch Ultra has been specifically designed for intense sports tracking. It is a larger model with better battery life. It also has a different body that should resist extreme weather conditions.

The case is made of aerospace titanium and is 49mm in size. It is much larger than typical watches, and also larger than existing Apple Watch models. The screen is completely flat and is made of sapphire crystal, which should increase sturdiness. It still has the familiar crown but there’s an additional action button to quickly access a range of features. For instance, you can use the button to mark a segment without having to fiddle with the screen. Buttons have been designed to be accessible even when you’re wearing gloves.
