Samsung’s round smartwatch isn’t expected to arrive for at least a few more months, but the company just leaked its own product ahead of time. A new SDK released on Tuesday, and spotted by SamMobile, reveals a ton of details about the upcoming Gear A.

As expected, the new Gear watch features a round design with a rotating bezel. The bezel can be used to scroll through lists, jump between screens, zoom in on an image, control the volume and more. Functionally, it seems pretty similar to the Apple Watch’s Digital Crown. Speaking of which, Samsung’s wearable features a crown button as well, though it’s unclear what it will do.

The SDK also reveals a bunch of specs and hardware. The “Next Gear” will apparently come equipped with a 360 x 360-pixel display at a resolution of 305ppi. It features Wi-Fi, GPS and a cellular connection. Finally, it comes packed with sensors, including a heart rate sensor, pressure sensor, a magnetic sensor, an accelerometer and a gyro sensor.

The SDK also comes packed with images of Samsung’s updated Tizen UI for the round watch face. There’s a refreshed fitness tracking app, a weather app, a voice recorder, a music player, messaging, a gallery app, settings controls and more. The software looks pretty simple for now, though it will probably get a nice polish before launch, and developers can create new apps using the SDK.

We expect Samsung to unveil the Gear A (or whatever Samsung calls its next smartwatch) in September during IFA, where the company will likely also announce the Galaxy Note 5.
