Along with the brighter display, the Ultra 2 is protected by a flat sapphire crystal. That is far more durable than the Ion-X glass found on the aluminum Apple Watch Series 10 models. The titanium Series 10 is protected by sapphire, but is priced similarly to the Ultra 2.

In the release announcing its Watch Series 10’s availability, Apple refers to the device’s “refined” design. It’s an accurate word for the device overall.

The Series 10 offers a design upgrade, adds one big new health feature – and sets the tone for the next 10 years of Apple Watch. But it won’t change the minds of Apple Watch skeptics.

Apple Watch Series 10 reviews are out ahead of its Friday release. Is the new Apple Watch worth it? Here's what experts have to say.

The embiggening of the Apple Watch is nothing new. The original Apple Watch measured 38mm and 42mm. The Series 4 bumped that up to 40mm and 44mm. The Series 7 made it 41mm and 45mm. Today, the Series 10 measures 42mm and 46mm. Normally, I rail against the trend toward larger watches, but the Series 10’s display is worth every millimeter.

As a result of a legal dispute that started in late 2023, the Apple Watch Series 10 is shipping without the ability to measure blood oxygen levels with a pulse oximeter. After removing the blood oxygen feature from the Series 9 and Ultra 2 in January 2024, Apple has yet to reach a desired outcome in its patent dispute with Masimo.

The new Apple Watch Series 10 is out. It has a subtly new design and cool new features. Should you choose this or the gorgeous new black Apple Watch Ultra 2? Read on.

Series 10 has the largest display of any Apple Watch to date, even bigger than the first Ultra. With up to 30 percent more screen area than Series 4, 5, and 6, and up to a whopping 75 percent more than Series 3, this is a game-changer for productivity and accessibility.
