The biggest new feature of the update is the introduction of blood oxygen saturation monitoring, which will allow users to keep better tabs on their overall fitness and wellness.

It uses both red and infrared lights and related sensors to measure the light reflected back from a user's blood, allowing the system to measure how much oxygen is in it. From there, the system uses custom algorithm in a new Blood Oxygen app to offer either on-demand measurements or periodic background monitoring — including during sleep.

Blood oxygen detection, long available on competing fitness trackers, allows users to automatically monitor the saturation of oxygen in their blood. That's handy for monitoring a user's ability to breathe during vigorous exercise, or to detect conditions such as sleep apnea while in bed.

Apple also says that it's partnering with researchers at the University of California, Irvine, and Anthem to study how blood oxygen levels can be used in future health applications. Another study will research how the Apple Watch's health sensors could detect early signs of respiratory conditions such as flu or coronavirus.

Performance & Display

The Apple Watch Series 6 also features an updated Apple Silicon S6 chipset. It's a dual-core processor based on the A13 Bionic, and delivers up to 20% faster performance 20% than the previous S6 chipset.

Apple also quietly introduced the U1 chip and Ultra Wideband support to the Apple Watch Series 6, meaning that it'll integrate with future Nearby Experiences and possibly Apple AirTags.

Like the previous Apple Watch Series 5, the new model also features an always-on display. Compared to the last model, Apple says the Apple Watch Series 6 display is up to 2.5 times brighter outdoors when the wrist is down.

The Apple Watch Series 6 also features improved battery life and charging speeds. Apple says it'll complete a full charge in just an hour and a half.

Built-in Altimeter

For users who hike or work out in elevated environments, Apple has included a new built-in altimeter with the Apple Watch Series 6.

The always-on sensor provides users with real-time elevation data by using an updated barometric altimeter combined with data from GPS and nearby Wi-Fi networks.

That means vastly improved measurements of small elevation changes, down to a single foot. It can also be shown as a workout metric or on an watch face complication.

New colors and accessories

Apple announced new color options for the Apple Watch, including a PRODUCT(RED) variant and a new blue finish. On the accessory front, the company debuted a new Solo Loop and Braided Solo Loop bands that are stretchy enough that users can take them on and off without any clasps.

Price and release

Apple Watch Series 6 prices start at $399 for the GPS only version and $499 for GPS and cellular. It's being offered alongside the Apple Watch SE priced at $279 and the Apple Watch Series 3 at $199.

Customers will be able to order the Apple Watch Series 6 starting on Tuesday. It'll start shipping out on Friday, Sept. 18.
