The Apple Watch Series 10 was revealed at the tech giant's Sept. 9 "Glowtime" event, alongside the new iPhone 16 series, AirPods 4, and plenty more. The wearable will come in three colorways: a deep, glossy jet black, warm rose gold, and classic silver aluminum.

Here are the new features that give Apple Watch Series 10 an edge over the last Apple Watch.

The Apple Watch Series 10, Apple's latest smartwatch model, has the following new features:

Largest and most advanced display ever for Apple Watch

The Apple Watch Series 10 is now larger with 42mm and 46mm sizes, up from 41mm and 45mm on the Series 9. The display has more rounded corners and a wider aspect ratio, which Apple says makes it appear softer, sleeker, and more streamlined. Plus, it'll have Apple's first ever wide angle OLED display, making it 40 percent brighter than past styles.

Thinner and lighter than ever before

Series 10 is the thinnest Apple Watch ever, at just 9.7 millimeters, which is almost 10 percent thinner than the Series 9. The Series 10 also weighs almost 20 percent less than the Series 9 and is made with 95 percent recycled titanium.

Faster charge, same battery life

Though the new Apple Watch Series 10 charges more quickly than past iterations, a full charge will only get you 18 hours of battery life at a time. A new design incorporates a more efficient charging coil that enables the watch to charge up to 80 percent in 30 minutes.

New sleep apnea detection

Approximately 1 billion people struggle with sleep apnea, a medical condition that affects breathing and can cause disrupted sleep. The new Apple Watch Series 10 (as well as the Series 9 and Ultra 2) has a sleep apnea detection feature that uses an accelerometer to monitor a metric called "breathing disturbances". It will notify you if it shows consistent signs of moderate to severe sleep apnea.

New built-in depth gage, water temperature sensor, and Tides app

A new Depth app launches automatically when the Apple Watch Series 10 is submerged and measures depths to 20 feet (six meters), as well as water temperature. A new Tides app shows seven days of information about rising, falling, high and low tides, sunrise and sunset for coastlines all over the world.
