The landmark feature is built-in cellular connectivity. Perfect for making calls, streaming music, receiving notifications, and interacting with Siri when you’re away from your iPhone. The Series 3 is available with and without cellular connectivity, starting at $399 and $329 respectively. Preorders start on September 15 with models shipping a week later.
In addition to the Apple Watch Series 3, Apple also announced a medical study, which will look at heart rates and arrhythmias. My wife, in particular, is really excited about this news. She’s been having occasional heart palpitations for the past several months and her doctors have been struggling to find their cause. This study, combined with the Heart Rate app’s notifications for unexpected elevated heart rates, might help her discover the cause of these palpitations.
