Take your temperature
The Apple Watch Series 8 is the direct successor to the Series 7, and while it doesn’t come with any significant design changes, it certainly is an upgrade. With a temperature sensor that can help you detect illness or help you with ovulation tracking plus the new Crash Detection feature, the Series 8 offers more health features than the previous generation.

Apple Watch Series 7
Some good deals out there
The Apple Watch Series 7 may be getting phased out by Apple, but that doesn’t mean it’s a bad watch. It has most of the features that the new Series 8 has, but it is missing Crash Detection and temperature sensing. Still, you could probably find a good deal on one if you wanted.
- Could get one on a good deal
- Only a few features short
- Older chip
- No Crash Detection
- No temperature sensors
Overall the Apple Watch Series 8 and Series 7 are pretty similar. They both have a ton of health features, fitness-tracking capabilities, and function as extensions of your iPhone to help you get more done. The biggest differences are the few key features Apple has added to the Apple Watch Series 8. Still, those features may not be worth upgrading for if you’re happy with your current Apple Watch Series 7. Let’s dive in and find out all the differences.
Apple Watch Series 8 vs. Series 7: Design, finishes, and colors
If you just glanced at the two models, you might be unable to tell them apart since the design is the same. Both models come in two case sizes — 41mm and 45mm — and are the same weight, meaning those extra temperature sensors in the Series 8 don’t mean you need to deal with a heavier watch.
The models differ in the options you have when it comes to finishes and colors. The Apple Watch Series 8 only comes in aluminum and stainless steel finishes, whereas the Series 7 also offers a titanium option. Of course, we know now that’s because the titanium finish is now reserved for the new Apple Watch Ultra (opens in new tab).
The Series 7 also had more color options on the aluminum models, offering blue, green, red, Starlight, and Midnight. The Series 8 has dropped the green and blue options but kept the red, Starlight, and Midnight, while also adding a silver option. Both models have the same color choices when it comes to the stainless steel models.
Apple Watch Series 8 vs. Series 7: Spec sheet
Once you get into the finer details, the differences between the two devices do become a little clearer and less cosmetic. The Apple Watch Series 8 has a few new big features, but it’s also got a big upgrade inside.
|Series 8||Series 7|
|Case sizes||41mm and 45mm||41mm and 45mm|
|Blood Oxygen app||Yes||Yes|
The Series 8 is an upgrade over the Series 7, and the brain that powers the device has a lot to do with it. The internal chip, the S8, is about 20% faster than the previous chip in the Series 7. You’ll get more done and a lot quicker on a Series 8, but that likely will only be noticeable to the select few who use their Apple Watch very heavily for communication, music, fitness tracking, and everything else.
Regarding features, the Series 8 packs in a few new heavy hitters that are worth noting. On to the next section!
Apple Watch Series 8 vs. Series 7: Features
First things first, the Apple Watch Series 8 can do everything the Series 7 can do. That means the Always-On display makes a comeback, fall detection hasn’t gone anywhere, and all the watch faces you’re used to having on your Series 7 are compatible with the Series 8. It’s the Series 7 that ow nlacks a few new key features.
Apple has included a temperature sensor in the Apple Watch Series 8, which is sensitive enough to sense a 0.1 degree Celsius temperature change in your body. The Series 8 takes your wrist temperature during sleep every five seconds, which Apple says can help you detect illness early and help a lot with ovulation tracking.
Thanks to two new and improved sensors — a 3-axis gyroscope and a G-Force accelerometer — the Apple Watch Series 8 will be able to tell when you are in a crash. Crash detection uses many sensors and features to determine if you’ve been in a severe crash, including the barometer, GPS, and microphone on your iPhone. When it does detect a severe crash, the Series 8 will automatically call 911, provide your location, and notify your emergency contacts if you don’t respond to the on-screen notification in 10 seconds. It’s very similar to fall detection, but for crashes instead.
Apple Watch Series 8 vs. Series 7: Battery life
While Apple announced a new Low Power Mode alongside the Apple Watch Series 8, it is a feature that will make its way down the lineup in watchOS 9. Any Apple Watch Series 4 and later will be able to take advantage of Low Power Mode as part of watchOS 9, meaning the Apple Watch Series 7 can take advantage of it too.
In Low Power Mode, the Apple Watch Series 8 and presumably other watchOS 9 devices could extend their battery life up to 36 hours depending on use — twice as long as using the Apple Watch in normal mode.
What exactly does it do to make the Apple Watch more power efficient? Apple has stated it temporarily disables or limits select sensors and features, including the Always-On Retina display, workout autostart, heart health notifications, and more.
Apple Watch Series 8 vs. Series 7: Should you upgrade?
If you just bought a Series 7, I’m not convinced the Series 8 is necessary to run out and grab right away for most people; however, a couple of new features could make it worth it to some.
If you’re someone who menstruates and you want better Cycle tracking and more precise indications of when you might be ovulating, the Series 8 might be worth it to you. Or, if you absolutely want the most features, you can get on your Apple Watch and think a temperature sensor and Crash Detection are worthy of your money.
Overall, I think there’s no question the Apple Watch Series 8 will take the mantle of best Apple Watch (opens in new tab) over the Series 7, but whether you want to ditch your Series 7 in favor of the Series 8 is up to you.
New watch on the block
The Apple Watch Series 8 will undoubtedly be the best Apple Watch for most people. While the design is the same as the previous generation, super important features like crash detection and the ability to sense your temperature make it a worthy successor to the Series 7.

Try and find a deal
With the same design and most of the same features as the Series 8, the Apple Watch Series 7 is still a great watch. Yes, the battery won’t last as long, and a couple of new health features aren’t on board; however, you might still be able to grab one at a significant discount.
