Apple Watch Series 9 vs. Ultra 2 Buyer's Guide: 25 Differences Compared

At its "Wonderlust" event in 2023, alongside the Apple Watch Series 9, Apple announced the Apple Watch Ultra 2. The Apple Watch Ultra is a relatively new kind of smartwatch from Apple with a focus on withstanding extreme environments, a high level of durability, extended battery life, and additional features to aid activities like diving and exploration.

Apple Watch Series 9 vs Ultra 2 Buyers Guide
Both the ‌Apple Watch Series 9‌ and the ‌Apple Watch Ultra 2‌ feature the S9 chip, a second-generation Ultra Wideband chip, an Always-On Retina display, IP6X dust resistance, and more, but there are significant differences between the two devices.

With as little as $50 between the 45mm stainless steel ‌Apple Watch Series 9‌ 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 41mm aluminum ‌Apple Watch Series 9‌ 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.

The Apple Watch Ultra offers specific capabilities to address the requirements of those who need their Apple Watch to provide assistance in challenging environments. If you need a more durable Apple Watch with features like a brighter display, louder speakers, a more reliable GPS, better water resistance, and more, the Apple Watch Ultra is undoubtedly the best choice.

The Apple Watch Ultra is also the largest and most feature-rich Apple Watch option available, not to mention that it offers the first true redesign of the device since its introduction in 2015. For technology enthusiasts, Apple Watch Ultra represents a way to get a new Apple Watch experience with the top specifications. Features like longer battery life and a larger, brighter display are also highly accessible, and will be beneficial to all users. As such, some customers may still be inclined to choose the ‌Apple Watch Ultra 2‌ over the ‌Apple Watch Series 9‌, even if they do not need it for use in challenging environments.

As the largest Apple Watch model to date, the size of the Apple Watch Ultra will not be for everyone. If you already prefer the 41mm Apple Watch casing size, the Apple Watch Ultra may be far too large for you. If in doubt, it may be worth heading to an Apple Store and trying on the Apple Watch Ultra in person to get to grips with the size and determine if it is too big and bulky for you.

Similarly, the Apple Watch Ultra's look may not appeal to some buyers. If you prefer the stainless steel Apple Watch and are looking for a more fashion-focused smartwatch that pairs well with premium bands, the more aggressive, rugged design of the Apple Watch Ultra may not be for you.

If the Apple Watch Ultra is out of your price range but you still want to use your Apple Watch in challenging environments, it is worth bearing in mind that the Series 9 still offers a durable design with a strong front crystal, water resistance, and many of the ‌Apple Watch Ultra 2‌'s software features like waypoint marking.

The ‌Apple Watch Ultra 2‌ has a lot to offer, especially for the subset of users who can take advantage of all of its capabilities, so it is certainly worth considering when purchasing a new model, but the ‌Apple Watch Series 9‌ is still a compelling all-around option that comes in at a lower price point with a subtler design.

It’s just too big for me. Especially thickness. I think the standard size is already as thick as I could stand. I’m glad people with bigger wrists have the option of the Ultra, but for me it’s just to large.

I'm not a pro user, I'm not a diver or mountain climber; but I did get the Ultra 1 last year. Why? I like the bigger screen. I love the battery life. I love the brighter screen. I see the "original" Apple Watches now and I can never go back. It's like going from a Ford to a Tesla back to a Ford. I highly recommend spending the extra $$$ on the Ultra if you wear your Apple Watch daily.

I wanted an ultra but the black/space gray never appeared. Hopefully next year. A little thinner would also be nice. I ended up going with the series 9

I was never really interested in apple watch before, but am now for medical reasons. This may just replace my current “fall” button and the ekg and oxygen level a bonus.

I have never come so close to buying something then deciding not to. I have a series 6 in blue and I’m going to wait another year for the series X. As much as I want it, the ultra is just too big for my 165mm wrist and I have no need for cellular(my carrier doesn’t even offer it). There’s not much in terms of upgrades that I’d use that either the 9 or Ultra offer over my 6 so I’m going to wait. It wasn’t easy and I truly hope next year will be an exciting year for the watch.
