ABC News has been given an unprecedented, exclusive look at Apple's top-secret lab inside its Cupertino headquarters which the company has been using for testing health, fitness and movement tracking features of the Apple Watch.
The broadcaster has now released a short video which offers a rare glimpse into the facility. Jay Blahnik, the key Nike FuleBand developer whom the iPhone maker hired more than two years ago to help develop the Apple Watch's fitness features, can be seen in the video discussing the purpose of the lab with ABC's Rebecca Jarvis.
