The Apple Watch Series 8 boasts features like a Always-On Retina display, blood oxygen monitoring, high and low heart rate notifications, temperature sensing, cycle tracking with retrospective ovulation estimates, emergency SOS, fall detection, crash detection, and cellular connectivity. It also comes in two sizes: 45mm and 41mm.

The Apple Watch SE offers similar features like a Retina display, high and low heart rate notifications, cycle tracking, emergency SOS, fall detection, crash detection, and cellular connectivity. It comes in sizes of 44mm and 40mm.

The Apple Watch Ultra seems to be the most advanced of the three, with a larger size of 49mm, higher water resistance (up to 100 meters), increased brightness on its display (up to 2000 nits), MIL-STD 810H certification for durability, an action button, blood oxygen monitoring, temperature sensing, cycle tracking with retrospective ovulation estimates, emergency SOS, fall detection, crash detection, and a loud 86-decibel siren for attracting attention.

All three watches are swimproof, have various health monitoring features, emergency capabilities, fall detection, and cellular connectivity options, but the Ultra model appears to have some additional ruggedness and more advanced specifications, including a larger size, increased water resistance, and greater display brightness.

Ultimately, the choice between these models might depend on your specific needs, preferences regarding size, desire for advanced features, and budget. If you're looking for a more rugged, larger watch with the most advanced capabilities, the Apple Watch Ultra might be the one to consider. The Series 8 and SE are also excellent options, catering to a slightly different set of preferences and needs.
