As you can notice, the smartwatch in the image does look a lot like the original Moto 360 but is actually a different device. Firstly, the original Moto 360 doesn’t come with the large extensions at the top and bottom of the watch. Second, the original model had the crown positioned slightly lower on the side of the watch. These differences indicate that the smartwatch seen in the image could actually be the successor to the Moto 360.
Since it is just a render, there is a possibility that the person who rendered the smartwatch may have made a mistake. However, it is also possible that Motorola deliberately tweeted the image to create hype for the Moto 360 successor that it is expected to unveil soon.
