Samsung has released a teaser video for its upcoming Gear 2 smartwatch ahead of its September launch. Indeed, it’s the same video that was shown briefly at the end of last week’s Galaxy Note 5/Galaxy S6 Edge+ announcement.

For those who haven’t seen it, the 30-second clip shows a variety of watch faces and hints at some of the functionality. While it doesn’t specifically name partners or apps, it does reveal a built-in heart sensor and possible Nike+ integration.

One interesting notion being tossed about today is that the video may be teasing a rotating bezel. Watch it closely and you’ll see instances where the grey trim appears to be rotating. Of course, this isn’t something Samsung has confirmed, but it’s an interesting concept nonetheless.

We might assume that a rotating bezel might be used for navigational purposes, sliding from app to app or function to function. Then again, the display is likely touch, too, and may negate the need for such hardware. Also possible… the bezel is not so much rotating as being hit with moving light, instead.

The Samsung Gear 2 is expected to debut at IFA in Berlin on September 3. Check back for more coverage as we get closer to the launch.
