The Series 4 will be available for order on September 14 and will hit store shelves on September 21.
Gottlieb and Shuren pointed to the FDA's digital health action plan unveiled a year ago, aimed at streamlining approvals for software posing a lower risk than traditional medical devices.
The back of Series 4 is made entirely of ceramic and sapphire crystal. Despite the physical overhaul, Apple still managed to wedge in a battery that will remain consistent with the Series 3's 18 hours of usage on a charge.
"We're humbled and inspired by how Apple Watch has become such an important and essential part of people's lives", said Apple's Jeff Williams. The speaker has also been redesigned as it is 50 per cent louder compared to previous-generation Watch Series 3. The microphone has been moved over to the other side to avoid conflicting when speaking to the Watch or taking a phone call. Is it worth upgrading to the latest Apple Watch if you have an older model?
We can also expect stainless steel models, and the usual Nike and Hermes collaborations. You can, for example, customise a watch face to have different time zones, or have it focus on health and fitness.
The most enticing feature of the new Apple Watch is that OLED display which is now over 30 per cent larger to reduce the bezels and max out the wearable's slightly larger (but also thinner) case size. The modular face can now surface more detailed information from stocks and healths apps. Thanks to a new accelerometer and gyroscope, it can detect when you slip or fill. Other additions include a "low heart rate" notification, alerts for atrial fibrillation, and electrocardiogram (ECG). This feature will be reaching to USA customers later this year followed by a wider rollout.
On heart health, you can already monitor your heart rate on Apple Watch. Prices start at $399 for the non-cellular aluminum models in space gray, silver and gold, and $499 for the non-cellular stainless steel models in silver, "polished graphite" and gold. If you're immobile for more than one minute, it will automatically make a call to emergency services for you. The device also sends a message along with location of the user to emergency contacts.
