The new Apple Watch Series 10 is here, boasting a bigger but thinner display that promises to be easier to read at a glance.

“It’s the thinnest Apple Watch ever, with our largest and most advanced display,” Apple COO Jeff Williams said at today's iPhone 16 event.

The Apple Watch Series 10 is available for preorder now and launches on Sept. 20, starting at $399 for the Wi-Fi model and $499 for the cellular version. Thanks to the larger display, which features 30% more screen real estate, the Apple Watch Series 10 can display slightly larger fonts and an additional line of text.

The new screen also operates as a wide-angle OLED display, meaning it can emit more light at an angle, making it easier to quickly glance at information when looking at the watch from the side. Williams calls the screen “the largest and most advanced display ever for Apple Watch,” saying it even slightly exceeds the 1.9-inch display size on the Apple Watch Ultra 2

The screen is 9.7mm thick, or about 10% thinner than last year’s Apple Watch Series 9. To pull this off, Apple miniaturized some of the internal components even more, including the speaker, which has been reduced in size by 30%. Despite the size reduction, the audio on the Apple Watch is powerful enough that the company will let customers play music and podcasts directly from the speaker itself, an apparent first.

In addition, the Watch Series 10 features an improved charging coil, enabling you to charge the device by up to 80% in a mere 30 minutes. The product will also come in either aluminum or a pricier polished titanium casing, with Apple seemingly ditching the stainless steel frames.

Inside the Watch Series 10 is the S10 chip to help power AI and health tracking features. This includes the device’s upcoming ability to detect if you suffer from sleep apnea by analyzing suspected breathing disturbances as you sleep. The company plans on enabling the capability later this month, pending FDA approval, on the Series 10, Series 9, and Ultra 2.

Despite all the enhancements, the Series 10 isn’t offering a major leap in terms of battery life. Expect the product to offer 18 hours of battery on a single charge, or the same amount as the Apple Watch Series 9.

Cupertino also didn’t reveal a new Apple Watch SE model or an Apple Watch Ultra 3. Instead, the company merely debuted a new “satin black” titanium color for the Ultra Watch 2, which is also available for preorder now ahead of a Sept. 20 launch.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
