Rumors, leaks, and what we know

The Apple Watch was initially pitched as an ambitious sequel to the iPhone. The original release was a mixture of a futuristic communication device, a tiny app-based computer, and a fitness tool, but it wasn’t spectacularly great at any of those skills. Thanks to years of refinement and a complete revamp of watchOS, we now have the wearable we know and love today: a health and fitness tracker that has deep integrations with Apple’s iPhone and subscription services.

Not a bad change, all told, but a pretty dramatic reduction in ambition when you consider how Apple imagined people would be sending each other recordings of their heart beat because of its smartwatch.

And yet, despite that gradual streamlining, the Apple Watch’s look has remained remarkably consistent across the last decade — until 2024, that is. If rumors and reports are to be believed, the Apple Watch Series 10 or “Apple Watch X” could be as dramatic a shift as the iPhone X was to the iPhone line. A refined look and new functionality for a new decade of the company’s smartwatches. Here’s everything we know about the next Apple Watch ahead of it getting announced later this year.

When will the Apple Watch Series 10 be announced?

Apple Watch announcements are typically bundled alongside the iPhone. The Apple Watch Series 9 was announced alongside the iPhone 15, the Apple Watch Series 8 was announced alongside the iPhone 14, etc. It’s a pattern that makes sense because, while a cellular Apple Watch or Apple Watch Ultra can be used on its own, these are fundamentally accessories to a smartphone, displaying smartphone notifications and controlling playback of media in smartphone apps, to name just two things the Apple Watch can be used for.

We won’t know a firm date until later this year, but considering Apple tends to announce its new smartphones in September before putting them up for preorder a few days later, odds are good that the Apple Watch Series 10 will be introduced at the same time.

What will be different about the Apple Watch Series 10?

A thinner watch body

The Apple Watch has gotten more compact over the last decade, but not nearly as small as a traditional watch, like a Timex Weekender, for example. Apple’s been able to enlarge the smartwatch’s display without radically changing the dimensions of the device’s two sizes, 41mm and 45mm. However, the sensors on the back of the watch that are meant to be placed on your wrist continue to take up a significant amount of space, increasing the watch’s overall thickness.

According to Bloomberg, the Apple Watch X or Series 10 will have a thinner watch case and a new way for watch bands to attach that could open up more room in the Watch itself. Ming-Chi Kuo, a reliable analyst tracking Apple suppliers, corroborates Bloomberg’s reporting that the Series 10 will get thinner, and also claims Apple could introduce new screen sizes too, taking the 41mm model to 45mm, and the 45mm model to 49mm. A larger screen is a year-over-year improvement Apple has pushed for in the past, but at 49mm, the Apple Watch Series 10 would be encroaching on the Apple Watch Ultra 2 “Big Watch” territory. And maybe that makes more sense if Apple views the 49mm Series 10 as the iPhone 15 Plus of its smartwatch family.

Adding more fuel to the big screen fire, leaked CAD files shared by 91mobiles suggest either the Apple Watch Series 10 or possibly, an entirely separate anniversary-edition Apple Watch, could ship with a larger two-inch screen. That would make it bigger than both the Apple Watch Series 9 and the Apple Watch Ultra 2. The actual shape of the watch in these CAD files doesn’t seem to reflect all the design changes that have been previously reported, so it’s possible this isn’t the final version of the watch, but if these are real, we have our first glimpse of Apple’s next smartwatch.

New magnetic watch bands

In that same report, Bloomberg claimed that the connector used to attach existing watch bands from the first Apple Watch to the Apple Watch Series 9 uses up a lot of space in the smartwatch that would be better spent on a larger battery or an overall reduced size. Apple has “explored a new magnetic band attachment system” that could alleviate the problem, but Bloomberg’s report cautions that it might not be ready in time for the Apple Watch Series 10.

Considering just how many watch bands Apple and third-party accessory makers have produced, switching to a new system, particularly one that sounds more expensive to manufacture and design around, isn’t a change to be taken lightly. Avid Apple Watch owners could be left with dozens of bands that don’t work at all if they decide to upgrade, for example. That’s never stopped Apple before, but it could certainly give a customer considering an upgrade pause.

A bright microLED display

Apple has been reportedly trying to develop its own microLED displays for years now to be less dependent on Samsung, who makes many of the displays for Apple’s various products. The Apple Watch was supposed to be the first place the company was going to test its homegrown displays, either on the Apple Watch or the Apple Watch Ultra.

Now, Apple has reportedly scrapped plans to use the brighter, more vibrant microLED Apple Watch display entirely because the displays “can’t add significant value to [the Apple Watch], and the production costs are too high to make it economically viable,” according to Ming-Chi Kuo. Analysts and leakers certainly get things wrong all the time about Apple’s plans, but for now it seems like a new display on the Apple Watch Series 10 is unlikely.

What we might get instead is a more power-efficient display. Apple already uses low-temperature polycrystalline oxide (LTPO) technology on the Apple Watch to display and update information on the screen even if the Watch isn’t fully lit up, and now, according to The Elec, Apple plans on using even more LTPO thin-filament transistors (TFT) in the next Apple Watch to offer a display that sips battery life rather than guzzles it. These transistors allow for precise control over how much light leaves a pixel in a display panel. Using more LTPO just means the screen will be even more efficient at low refresh rates, which is what the always-on display feature of the Apple Watch depends on.

Another possible contributor to better battery life could be the inclusion of an entirely new type of battery. TDK, one of Apple’s suppliers, recently announced that it successfully developed a material for solid-state batteries that is dramatically more energy-dense than existing solid-state and traditional lithium-ion options. TDK’s new solid-state material has “an energy density of 1,000 Wh/L, approximately 100 times greater than the energy density of [its] conventional solid-state battery.” If it shows up in an Apple Watch, that could make a huge difference.

New health detection and safety features

Using the Apple Watch to offer a non-invasive way to monitor blood glucose remains Apples white whale. In the meantime, the company is reportedly planning to use the Apple Watch’s ability to measure respiration to detect sleep disturbances and let you and your doctor know if you could have sleep apnea. More potentially useful data to be considered in the Vitals app Apple is adding in watchOS 11.

Apple is also planning on introducing the ability for the Apple Watch to detect elevated blood pressure and log it into a “blood pressure journal” that can be filled out with details about what was happening when the elevated blood pressure was detected. This is reportedly the first step towards a much more in depth measurement system that could ultimately inform your doctor or cardiologist of your “exact systolic and diastolic measurements,” according to Bloomberg.

Apple / Pocket-lint

Safety is a key component of what Apple sells with the Apple Watch and heart health is really only one part. Fall detection, added with the Apple Watch Series 4, and car crash detection, introduced with the Apple Watch Series 8, expanded the scope of what the smartwatch can detect. Now, based on a patent spotted by Wareable that Apple filed in March 2024, it looks like a future Apple Watch could also be used to detect drowning.

The Apple Watch can already determine when someone is swimming for workout tracking, but Apple’s patent suggests the same sensors built in to the smartwatch could also detect “irregular behavior” in the water and notify people nearby that something is wrong. It’s not clear if the feature will be part of the Apple Watch Series 10, but it would fit in nicely with what the smartwatch can already do.

Will blood oxygen monitoring be on the Apple Watch Series 10?

The feature hasn’t been added back in

Apple opted to sell modified versions of the Apple Watch Series 9 and Apple Watch Ultra 2 that had blood oxygen measurements disabled to get around the International Trade Commission ban that was put into place after a US ITC judge ruled that Apple was violating health tech company Masimo’s blood oximetry technology patents, a whole legal mess you can read about in detail in our article on the ban.

Since then, Bloomberg has reported that Apple engineers were working on changes to the algorithms used for blood oxygen calculations that could allow the company to move forward without having to change the hardware of the Apple Watch. Whether those changes actually make it to this year’s Watches remains to be seen.

When will the Apple Watch Series 10 be available for purchase?

Expect a fall launch

We won’t know for sure until Apple’s fall event, but as a rough estimate, if Apple announces new phones and smartwatches on a Tuesday in Sept., they’re typically available to pre-order on Friday.

As to what they’ll cost, it seems likely Apple will keep the entry-level $399 price the same, since it’s already selling the Apple Watch Ultra at $799. The iPhone X was used to raise the price of Apple’s high-end iPhones to $999 starting in 2017, but that was before the company began separating features and components between normal iPhones and “Pro” and “Pro Max” tiers.

Is it still a good time to buy an Apple Watch Series 9?

Not unless you’re getting a deal

If you’re at all interested in the new design and possibly exclusive new health tracking features on the Apple Watch Series 10, it’s worth the wait. In fact, because Apple is rumored to be moving to a new type of watch band, waiting will also save you from investing in watch parts that won’t be useful the next time you buy a new watch, too. Only choose the Series 9 if you’re getting a meaningful discount.
