When you try to figure out why the Ultra 3 costs so much more than the Neo, let alone its Watch siblings, things get trickier for Apple. Take a look at this official comparison page for the Apple Watch. If we allow ourselves to discount iterative improvements (brighter screen, better speakers, bigger battery, better GPS, etc) and concentrate on what you can only get on the Ultra and not on the Apple Watch 11 or Watch SE, we're left with just these: emergency SOS via satellite, scuba diving features, a siren, and a titanium build with sapphire crystal. Now consider the Series 11 starts at $399, and the SE at $249. All boast the same S10 chip, which in 2025 wasn't even updated over the Series 10. That's a mighty big premium on the Ultra.
