Apple today introduced three new Apple Watch videos on its YouTube channel, highlighting third-party apps designed for the wrist-worn device. Each of the three videos focuses on a different subset of apps, covering music, fitness, and travel.

The videos all depict a single Apple Watch that displays a series of apps on the screen, with a selection of app icons in the surrounding space. Icons are enlarged to denote which app is on the screen.

In the "Music" video, for example, music discovery app Shazam, DJing app Pacemaker, and ticket-purchasing app StubHub are shown in quick succession.

The "Fitness" video highlights the Nike+ running app, the WaterMinder hydration tracking app, and sports scores provided by the MLB.com At Bat app.

The third and final video, "Travel," gives a brief glimpse of travel app Expedia , transportation requesting app Uber , and recommendation app Yelp

Apple's newest short advertisements are the company's first that put third-party apps for the device directly in the spotlight. Previous ads have focused on showing off the different use cases for the device, including four videos released last week that depicted the Apple Watch being used in daily life while traveling, working out, and communicating with friends and family.
