Apple Watch Ultra 4 vs Watch Ultra 3: Should you really spend another $799?

· By Endurance Wire

A quick glance at the spec sheet and it looks like the Apple Watch Ultra 4 is quite similar to last year’s Ultra 3. The same 49mm titanium case houses the same big 3,000-nit display, with the Action button on the side, satellite connectivity, 100-meter water resistance, and recreational diving support down to 40 meters. Apple hasn’t even changed the two case colors. But that’s just the hardware side of the story. Look underneath the familiar casing, and things start looking a lot newer. The Ultra 4 introduces an entirely new Health Sensing System, higher-frequency heart-rate and HRV measurements, and so much more.
