Samsung was early to the recent smartwatch craze, but its products haven't exactly sold like gangbusters. While Samsung has made an Android Wear watch, it seems more interested in moving forward with its Tizen-based Gear platform, and the new Gear SDK offers a lot of detail about that next device. It'll be round, but that's not the only thing we know.
The watch will have a 1.18-inch round display with a resolution of 360x360. That's not very large, but the overall device will probably be much less ridiculous as a result. Samsung is planning to use a metal frame with a large crown button that makes the device look more like a real watch. Its past smartwatches have looked very much like pieces of technology.
The new watch will come in both 3G and non-3G versions. It will also pack the usual WiFi, Bluetooth, GPS, heart rate monitor, and so on. According to Samsung's documents, it won't have an ambient light sensor. The SDK also includes a lot of UI examples, most of which look unsurprisingly like the Gear OS on a round display.
Interestingly, the UI examples make it clear the bezel of the watch will rotate, allowing you to control the interface without touching the screen. You could scroll through lists, change the volume, or control media playback by twisting the bezel.
The watch is only referred to in the docs as "The Next Gear," which I imagine is a placeholder, but never put anything past Samsung. It's apparently code named Project Orbis and is expected to be unveiled at IFA 2015 in a few months alongside the Note 5. You can expect it will only work with Samsung Android devices.
