Apple Watch Series 4 gets a badly needed facelift

You can order the Apple Watch Series 4 starting Friday, Sept. 14 and it'll be in stores on Sept. 21. 

The watch will start at $399 in the US with GPS and $499 with a cellular signal. 

We had the chance to take a look at the new Series 4.

The watch will detect if you have an elevated heart rate. 

It can even tell if you've taken a fall. 

Is uses a built-in accelerometer to sense a type of motion typically associated with a fall. 

It can call emergency services if you do fall. 

It can even take an electrocardiogram.

Hold your finger on the crown so the watch can detect your heart rate. 

It also has a much bigger screen than its predecessors. 

The crown will give haptic feedback when you control the watch. 

With the release date right around the corner, we'll soon know much more about how well the new Apple Watch fares in the real world.
