Design Comparison

Both smartwatches have a rectangular frame inspired by the refurbished Apple Watch 5, which, from a distance, makes them look quite similar. However, upon closer inspection, changes start to become more noticeable.

The Apple Watch Ultra comes with a complete Titanium casing with a Sapphire crystal cover for the display, rather than the Aluminium frame with Ion-X Glass found in the Series 8. This substantially increases the former's durability without needing a case.

On the right-hand side of both devices, you'll also encounter a digital crown, an component slightly larger on the Watch Ultra to complement its bigger size. 

One key fact that has changed between the two devices is an Action Button exclusive to the Apple Watch model, allowing you quick access to the Siren, workout features, and more with just a simple press. This might seem small to some, but you'll soon notice a difference when you're attempting to scroll through various apps in a rush.

Verdict:  Though both come with fantastic designs, if we were going to choose, it would be the watch Ultra all the way just based on the extra Action Button alone. 

Display Differences

As mentioned previously, the refurbished Apple Watch Ultra arrives in a slightly larger frame than the Series 8, measuring 49mm instead of the 41mm or 45mm found in standard Apple Watches.

Some might perceive this as being too large for small wrists; however, aside from this concern, its larger size offers significantly more viewing space than the Series 8, facilitating easier scrolling and tapping than ever before.

Regarding technical display elements, both designs come with the same Always-on Retina LTPO OLED screen, which allows you to view content even during downtime to save battery life. However, the Ultra variant again takes everything up a notch, offering an extra 1000 nits of peak brightness over its more affordable counterpart. Find out more about the Ultra's specs here.
