New Apple Watch announced with LTE

Apple Watch Series 3 launched

Williams says that Apple Watch is looking to track afib. By the way, this is something Fitbit has said it's looking into as well, along with sleep apnea.Apple Watch can now also detect arrhythmia, when your heart beats irregularly.

Apple Watch is now the number 1 watch in the world, above Rolex, Fossil, Omega, Cartier.

"Since the launch of the Series 2, Apple Watch has experienced phenonomeal growth." Up 50 percent year over year.

Tim back onstage. "Let's get going." Starting with the Apple Watch.

"So what's next? We're going to invest in online, and continue to reinvest in our classic locations, including Fifth Avenue." Opening up the plaza to allow more natural light, and glass cube will return when it reopens later.

Angela Ahrendts from Apple Retail onstage.

"We'll start moving into Apple Park later this year. It's more of a process, and the first step is the opening of the Steve Jobs Theater."

"You are in our prayers. Apple is working closely with relief and recovery efforts through Hand in Hand and the American Red Cross. We're making it simple to contribute through the App Store."

Cook says Jobs envisioned campus a decade ago. (Jobs didn't present the plans for the campus to Cupertino City Council until June 2011 — just a few months before he died.)
