There’s more variety than ever in the Apple Watch lineup thanks to the new Ultra model and updated SE. That means there’s a lot to consider between the latest wearables and also their predecessors. Read on for a detailed look at Apple Watch Ultra vs Series 8 vs SE, and more to figure out what’s the best pick for you or someone you’re shopping for.
Since Apple Watch isn’t necessarily an every-year upgrade, we’ve included everything from Apple Watch Ultra down to Series 6 and SE 1st gen to give the best perspective on the differences between all the recent models.
Apple Watch Ultra vs Series 8, SE, and earlier
Processor, storage, more
Last year, Apple used the same 64-bit dual-core processor in the Series 7 that launched in the Series 6, but with the updated S7 name.
This year, the Apple Watch Ultra and Series 8 come with the S8 SiP 64-bit dual-core processor. It appears to be roughly the same as the S7 and S6 performance-wise as Apple didn’t share any claims of performance advancements during its keynote or on its website.
While you shouldn’t expect a noticeable speed bump from Series 6 or 7 to 8 or Ultra, if you’re coming from an earlier Apple Watch model you should notice a faster, more responsive watch.
Apple does say that the S8 is 20% faster than the S5 chip.
Another benefit, if you’re coming from a Series 3 or 4 to Ultra, Series 8, or SE gen 2, is a jump in storage to 32GB.
| Ultra | Series 8 | SE 2 | 7 | 6 | SE 1 | |
| SiP/Processor | S8 SiP 64-bit dual-core processor | S8 SiP 64-bit dual-core processor | S8 SiP 64-bit dual-core processor | S7 SiP 64-bit dual-core processor | S6 SiP 64-bit dual-core processor | S5 SiP 64-bit dual-core processor |
| U1 (ultra wideband) | ✅ | ✅ | ❌ | ✅ | ✅ | ❌ |
| Bluetooth | 5.3 | 5.3 | 5.3 | 5.0 | 5.0 | 5.0 |
| Storage | 32GB | 32GB | 32GB | 32GB | 32GB | 32GB |
One more difference between Apple Watch Ultra/Series 8 and SE 2nd gen is the latter doesn’t come with the U1 ultra wideband chip.
Case and display
Apple Watch Ultra comes with the biggest case and display yet from Apple with 49mm for the former and a 410 x 502 resolution display that offers 1164 sq mm. Apple says it’s 27% bigger than the display on Series 4-6/SE.
Meanwhile, Apple Watch Series 8 carries on with the same sizes that launched with Apple Watch Series 7. That’s 45 and 41mm cases and a larger display that’s 20% bigger than Series 4-6/SE and 50% larger than the Series 3 display.
| Ultra | Series 8 | SE 2 | 7 | 6 | SE 1 | |
| Case size | 49mm | 45/41mm | 44/40mm | 45/41mm | 44/40mm | 44/40mm |
| Display size | 410 x 502 pixels, 1164 sq mm | 396 x 484 pixels, 1143 sq mm (45mm model) | 368 x 448 pixels, 977 sq mm (44mm model) | 396 x 484 pixels, 1143 sq mm (45mm model) | 368 x 448 pixels, 977 sq mm (44mm model) | 368 x 448 pixels, 977 sq mm (44mm model) |
| Brightness | 2,000 nits | 1,000 nits | 1,000 nits | 1,000 nits | 1,000 nits | 1,0000 nits |
| Always-on display | ✅ | ✅ | ❌ | ✅ | ✅ | ❌ |
| Sapphire crystal front | ✅ | Yes with steel models, no with aluminum | ❌ | Yes with steel models, no with aluminum | Yes with steel models, no with aluminum | ❌ |
Apple Watch SE 2nd gen features the same 44 or 40mm case options and the same display size as the 1st gen/Series 6 and earlier.
Apple Watch band compatibility
When it comes to bands, Apple says those designed for 44 and 45mm Apple Watches will work with Apple Watch Ultra and vice versa:
And with the Series 8 and SE 2nd gen using the same form factors as before, all bands for the correct sizes will continue working.
Battery life and charging
A major change with Apple Watch Ultra is the biggest battery yet in the lineup. That’s 36 hours of standard battery life and up to 60 hours of extended use with Low Power mode.
Notably, the Low Power mode will come to Apple Watch Series 4 and later and will double the battery of those models from 18 to 36 hours.
| Ultra | Series 8 | SE 2 | 7 | 6 | SE 1 | |
| Battery life – standard | 36 hours | 18 hours | 18 hours | 18 hours | 18 hours | 18 hours |
| Extended battery with Low Power mode | 60 hours | 36 hours | 36 hours | 36 hours | 36 hours | 36 hours |
| Charging | 0-80% in 45 minutes | 0-80% in 45 minutes | 0-80% in 45 minutes | 0-80% in 45 minutes | 0-80% in 60 minutes | 0-80% in 60 minutes |
First introduced with Apple Watch 7 and continued with Apple Watch Ultra and Series 8 is 33% faster charging than Series 6 and earlier. That means going from 0-80% in 45 instead of around 60 minutes for the other models.
If you’re interested in using Apple Watch Ultra, Series 8, or 7 for sleep tracking, you also get 8 hours worth of use from an 8-minute charge.

Apple Watch Ultra vs Series 8 and earlier wrap-up
