The Apple Watch Series 10 arrived a year after the Apple Watch Ultra 2, introducing a revamped design and a more advanced display. Apple did not launch an Apple Watch Ultra 3 this year, leaving last year's Apple Watch Ultra 2 as the latest version, so how does it compare to the latest Series 10 model?

Both the Apple Watch Series 10 and the Apple Watch Ultra 2 feature sleep apnea detection, speaker playback, a second-generation Ultra Wideband chip, an Always-On Retina display, IP6X dust resistance, and more, but there are still some significant differences between the two devices. Since the Series 10 is a year newer than the Ultra 2, it boasts a limited number of superior features, but the Ultra 2 remains the overall more capable device. The Apple Watch Ultra focuses on withstanding extreme environments, a high level of durability, extended battery life, and additional features to aid activities like diving and exploration.

With as little as $50 between the 46mm titanium Apple Watch Series 10 and the Apple Watch Ultra, some prospective customers will be weighing up whether it is worth spending a little extra to get the 49mm Ultra model. While there is a $400 difference between the GPS-only 42mm aluminum Apple Watch Series 10 and the Apple Watch Ultra, the high-end model offers a set of features to address specific challenges, so it may even be worth it for some of these buyers. Key differences between the devices include:

One of the most important differences between the Apple Watch Series 10 and Ultra 2 is their design, with the latter boasting a much chunkier, aggressive look with a flat display. The Apple Watch Series 10 has a much subtler appearance and is available in wider range of finishes, but which look you prefer is ultimately a matter of personal preference.

Ways the Apple Watch Series 10 Is Better

While the Apple Watch Series 10 does have some hardware improvements over the Apple Watch Ultra 2, such as a reengineered metal back with a larger charging coil and an integrated antenna, and a more compact chip, these are not really outwardly noticeable. The most noticeable enhancement is an updated display, which features a faster refresh rate to enable a live ticking seconds hand on certain watch faces. The display is also up to 40% brighter then viewed at an angle, making it easier to glance at the time or complications.

The Apple Watch Series 10 continues to be thinner, lighter, and cheaper than the Apple Watch Ultra. It also charges twice as quickly, but with a considerably shorter battery life.

Ways the Apple Watch Ultra Is Better

The AWU ultra is too big for my taste, as is the new 10. I've tried on both in the Apple Store.

Guess I'll stick to my 6 for another year, or a few more...or just move back to Garmin. I have very thin frame, and I just don't want a huge watch. Maybe the smaller 10?

What to do? 🤷🏻‍♂️

The only place I'd prefer Ultra over S10 will be for the battery. In everything else, S10 is just better. (some stuff personal preference, rest are facts when it comes to specs)

I went to the Apple Store a few weeks ago to compare the titanium Series 10 to the black Ultra 2. I fully expected when I tried on the Ultra I would not like it because it would be too heavy or bulky. I stood corrected - I was immediately smitten and never even tried on the Series 10. I absolutely love the Ultra. It’s a different form factor from the style I’ve had for the last decade, I love the ruggedness of it and the Alpine strap, the unique Ultra watch faces, and the very long battery life. It’s light and comfortable because of the titanium casing, and sleeping with it to track my metrics hasn’t been an issue. I’m once again excited about the Apple Watch after purchasing the Ultra.
 
Not going to buy another Watch until you bring back the pulse ox functionality.

The series 10 Apple Watch is very appealing, but my AW Ultra 1 has blood oxygen. I’ll wait a few more years.

In the US, Apple needs to settle their patent dispute to bring it back. The feature is turned off via software. Once the patent issue gets resolved an OS update to the watch will bring it back. If you live outside the US, blood ox works.
 
I got the Ultra 2 last year and love the battery and the O2. I usually upgrade every year, but didn't consider it due to the O2 being active on my current one. Yes, the 10 screen size looks nice and the new color on the Ultra 2 but the tradeoffs aren't worth it. I'll see what happens with the Ultra 3 and the series 11, but it would need other meaningful upgrades to not have the O2.
 
AWU2, mainly because of the new Ultra milanese band which is simply the best band Apple has put out to date. Extremely comfortable, light weight, strong, doesn't stain, waterproof (built for diving), easily adjustable and secure. Plus it looks awesome and the metal matches perfectly to the watch. That plus the battery life, the best watchface options, larger/nicer crown for scrolling and flat screen which make it way easier to tap out messages replies. Action button is just a bonus but nice to have.

It would have been a closer call for me if the S10 always on seconds hand wasn't a gimmick baked into only the two new watchfaces. We'll have to wait for watchOS 11.1 to see if Apple cares or if they are fine with shipping hardware with half-baked features now.
