Apple chief operating officer Jeff Williams said the company is taking the Apple Watch to the next level with the newest generation of the device, improving functionality across multiple areas.
It's strong, dynamic and colorful and the new Watch faces really add to the mix.
The Apple Watch Series 4 will be available from 21 September at $399 for the Global Positioning System model and $499 for the LTE version. Apple Watch Series 4 also ships with a new user interface that has been optimised for the larger display.
Apple said the new fall detection feature "Requires a tremendous amount of data and analysis".
Not just that. but the watch's new ECG feature measures heart rate and will let you know if anything is irregular or potentially risky.
U.S. Cellular has announced that pre-orders for the Series 4 will start on September 14 on its online store and area U.S. Cellular stores.
But, the new processor and speed doesn't come at the cost of battery life, with a claimed 18 hours of use between charges. Diehard Apple Watch fans can breathe easy: The 40mm and 44mm versions look almost identical in width compared to their 38 and 42mm predecessors.

The most noticeable change coming to the Series 4 is the redesign of the chassis.
In its short existence, Apple Watch has gone from a niche wearable to become the most popular watch in the world. However, as some rumors did suggest previously, a circular Apple Watch model was not released this year.
The all new Apple Watch 4 features a bigger screen, all new features and several great reasons to place your Apple Watch 4 pre-order this week. And last, Apple Watch Series 4 can diagnose your heart rhythm.
There are new heart rate notifications as well.
On the software side, Apple has revamped its apps to make them fit the new screen.
The heart rate monitor is back in the rear, but in addition to an optical sensor, there is now an electrode array in the digital crown to produce electrocardiograms - endorsed by the American Heart Association and approved by the Food and Drug Administration.
The Apple Watch Series 4 (GPS) starts from $599 and Apple Watch Series 4 (GPS + Cellular) starts from $749 both featuring the updated design and new health capabilities.
Apple's also made internal improvements to the Apple Watch Series 4 that won't be obvious when looking at the wearable, but should be when using it. What's more, it also has a built in ECG - the first consumer product available over the counter to do so.
