The Apple Watch Series 10 improves on our favorite smartwatch with a bigger screen and new sleep health tracking, though not everyone needs to rush out and upgrade.

Just like the iPhone X, the Apple Watch Series X—as it was rumored to be called—was expected to mark a major milestone for Apple’s decade-old wearable. It was rumored to bring radical changes, including a new flatter design with a much thinner case along with a new magnetic band attachment mechanism.

The new Apple Watch Series 10 features a larger display, thinner profile, and faster charging for those who want round-the-clock battery life. Consumer Reports reviews the model.

Apple released Apple Watch Series 10 with a new Jet Black color. Customers are already complaining that this new finish easily scratches.

You can get the new Apple Watch in a variety of band and casing choices. This series introduces a jet black case — the Apple Watch’s first polished aluminum finish — with options of a black sports band or ink sports loop.

While we did track some light deals on the new Apple Watch Series 10 during the pre-order phase at Amazon, it is now offering the best straight up cash deal yet on the Jet Black 46mm Apple Watch Series 10 at $399 shipped.
