Apple Watch 8 vs. Apple Watch SE: How do they compare?

Plenty of smartwatches are out there, from the new Samsung Galaxy Watch Ultra to the Google Pixel Watch 2 to the Fitbit Versa 4. Despite all of those options, Apple Watches still corner the market of smartwatches. Apple comes out with updates and new versions of its watches pretty often, and they all vary greatly in terms of pricing — especially on Prime Day when deals abound.

While the Apple Watch Series 8 ($399) and Apple Watch SE ($249) are pretty darn similar, there are some important differences between the two. If you're doing your research before you buy this Prime Day, good for you! Based on my and my coworkers' experiences with them both, here's what you need to know about the comparison between the Apple Watch SE and the Apple Watch Series 8. (One thing to note: The Apple Watch Series 8 is an older model and has limited availability. It may only be available as refurbished or through a third-party seller.)

Battery life and detection

Most Apple Watches have similar battery life, and the Apple Watch Series 8 and the SE each have about 18 hours of juice. Both watches support low-power mode, but the Series 8 has faster charging. Both have access to 32GBs of memory.

The Series 8 has crash detection and temperature sensors, accelerometers, GPS, and a heart rate monitor. The SE, on the other hand, only comes equipped with a second-gen optical heart.

Health features

I use my Apple Watch almost exclusively for fitness tracking. I need to close my circles, I need to track my runs, and I simply must reach 10,000 steps a day. The Apple Watch SE has everything I need to do just that: notifications if your heart rate is high, low, or irregular, cardio fitness levels, cycle tracking, and sleep tracking. For me, that's plenty. But if you're really into tracking, the Apple Watch 8 offers more, like blood oxygen, nighttime wrist temperature deviations, and retrospective ovulation estimates.

For me, the Apple Watch SE wins this round, but for those who are more health data-obsessed, the Series 8 might come out on top because it simply has more to offer.

Screens

Both watches are available in two sizes. The Apple Watch Series 8 has a 904 sq mm display area or a 1,143 sq mm display area, while the SE has either a 759 sq mm or a 977 sq mm display area. Put more simply, Series 8 watches can be way, way bigger if that's what you're looking for.

Personally, I have great eyesight (20/20) and prefer the way a smaller watch looks on my wrist, so I prefer the cheaper SE. However, others with bad eyesight and other fashion preferences might have differing opinions.
