The Series 8 has more health-tracking features than the SE, such as its new wrist temperature measurements, blood oxygen saturation readings and the ability to take an electrocardiogram. The SE does not have these features, although it does feature some health-tracking capabilities such as tracking workouts, detecting hard falls, measuring heart rate, and mirroring iPhone alerts.
The Series 8 is available in a pricier stainless steel finish, and the aluminum version comes in an additional Product Red color option not available on the SE.
Finally, there is the ultra-wideband chip. The Series 8 has an ultra-wideband chip, which is not present in the SE. This chip could be useful for unlocking your car with your phone or watch, as well as for other features.
