You can interact with the flexible 4-inch flexible OLED display in a couple of ways. I mostly swiped up and down and back and forth through the various menus using my finger. But you can also wave your had over the Nubia to navigate screens.
The Nubia Alpha has four main menus, each in a different color. Swipe to either side to scroll through them.
There is a built-in heart rate monitor and numerous fitness features for recording workouts, sleep tracking and step tracking (which worked okay).
You'll either love or hate the looks. Some people I showed it to thought it was a house arrest bracelet.
There is a 5-megapixel camera that take pretty bad photos. They look like they are from an iPhone 3GS.
Besides taking photos, you can also record 10-second long video clips. But because of the camera's placement framing for photos and videos looked horrible.
The Nubia Alpha watch is now on sale for $449. The US version connects via bluetooth while the Chinese version has an eSIM for making phone calls.
