Apple Watch Series 3 Won't Be Getting WatchOS 9

When it arrives this fall, Apple's watchOS 9 will work on the Apple Watch Series 4 and later. The Series 3, which debuted nearly five years ago, is left out of the party.

Bad news, Apple Watch Series 3 owners: Your smartwatch will not be receiving the next major watchOS release. 

Announced Monday, Apple watchOS 9 will bring a number of new health and fitness features, plus four fresh watch faces, to Apple Watches this fall. The updates include expanded atrial fibrillation (AFib) detection capabilities, a new Medications app to help you manage your prescriptions, running-specific metrics, a Multisport workout type for triathletes, and more. 

Unfortunately, the update will not be available on the nearly five-year-old Apple Watch Series 3, which first hit the market in September 2017. Scroll all the way down to the Availability section of Apple's watchOS 9 press release, and the news is right there: "watchOS 9 will be available this fall as a free software update for Apple Watch Series 4 or later paired with iPhone 8 or later and iPhone SE (second generation) or later, running iOS 16," Apple writes.

In other words, watchOS 9 will work on the Apple Watch Series 4, the Series 5, and the Series 6, models Apple has stopped selling but continues to support through software updates, as well as the Watch SE and the Series 7. The Series 3 is left out of the party.

If you still rock a Series 3, this is probably less of a shocker than a bummer. While watchOS 8, the current version of Apple's smartwatch operating system, is available on the Series 3, some newer features are unsupported, including the Portraits watch face. In addition, automatic cycling detection, which requires Apple's latest-generation motion sensors, only works on Watch SE, Series 6, and Series 7.

At the time of this writing, Apple is still selling the Series 3 for $199 as a more affordable alternative to its latest flagship smartwatch, the Series 7 and the two-year-old Watch SE, which start at $399 and $279, respectively. Given that it's ending software support for the Series 3, we don't expect Apple to keep making and selling it for much longer. If history is any indication, this fall will likely see a major shakeup to Apple's smartwatch lineup, with the company finally discontinuing the Series 3, replacing the Series 7 with a new flagship, and possibly lowering the price of the Watch SE. 

If you're in the market for an affordable Apple Watch right now, we don't advise purchasing the Series 3. The Watch SE, on the other hand, is a solid budget-friendly option, offering many of the same key features as the Series 7, with the exception of an always-on display, a blood oxygen saturation (SpO2) sensor, and electrocardiogram (ECG) support.

We can't make any promises, but if you can delay your Apple Watch purchase until this fall, you might be able to snag the SE for $199.

My Experience

I'm PCMag's managing editor for consumer electronics, overseeing an experienced team of analysts covering smart home, home entertainment, wearables, fitness and health tech, and various other product categories. I have been with PCMag for more than 10 years, and in that time have written more than 6,000 articles and reviews for the site. I previously served as an analyst focused on smart home and wearable devices, and before that I was a reporter covering consumer tech news. I'm also a yoga instructor, and have been actively teaching group and private classes for nearly a decade. 

Prior to joining PCMag, I was a reporter for SC Magazine, focusing on hackers and computer security. I earned a BS in journalism from West Virginia University, and started my career writing for newspapers in New Jersey, Pennsylvania, and West Virginia.

The Technology I Use

My little Florida beach bungalow is brimming with smart home tech. I have a smart speaker or display in every room, allowing me to control other connected devices by voice. The Nest Hub on my bedside table lets me set wake-up alarms, control my smart light bulbs, and set the temperature on my smart thermostat. I use the Amazon Echo Show 8 on my kitchen counter to browse recipes, reorder protein powder, check the weather, and watch the news while I do dishes. 

Because I suffer from allergies, air purifiers are essential. My favorite model is the Dyson Purifier Cool TP07, which doubles as a fan and continuously sends indoor pollution data to its companion mobile app. 

My pitbull Bradley sheds, so a good robot vacuum is a must. I currently use a premium Ecovacs Deebot that can both vacuum and mop, empty its own dustbin, and wash its own mop cloth. 

For fitness, I like to mix up my routine with cycling, indoor rowing, running, and strength training in addition to yoga. I take classes on the Tonal 2 smart strength training machine, I row indoors on an Aviron machine, and track my beach runs with an Apple Watch while listening to music on my Apple AirPods Pro. On the weekends, I love riding e-bikes like the rugged, beach-friendly Aventon Aventure for fun and fitness.

My job involves a lot of virtual meetings, so a quality webcam, microphone, and ring light are important. I use the Jabra PanaCast 20 webcam, the Elgato Wave: 3 microphone, and a Yesker tripod ring light. 

As for my preferred phone platform, I'm an iPhone person, but I've also extensively used Android for product testing.
