Incident Detection or Fall Detection
Incident detection is a useful feature on the smartwatches. When the wearer of the watch experiences a hard fall, the smartwatch detects the fall. It automatically starts the incident detection program. First, it tries to get a response from the wearer. If the weares does not respond to the automatic messages of the smartwatch, the smartwatch sends in emergency message with the geo-location data to the designated contacts of the watch owner. Apple Watches can go a step further and send in message to the emergency services of your country to seek emergency help.
If your Apple Watch SE has cellular support, the watch will send an emergency SOS message through the watch’s cellular network. Else, it can make use of the cellular network of the phone that is paired with the Apple Watch SE. But the phone would need to be nearby to the watch. As an alternative, if your phone supports wifi calling, the watch can make use of the Wi-Fi network to seek emergency assistance for the wearer.
Incident detection feature has been proven successful on Apple watches. Apple Watch SE also supports the incident detection feature. If you intend to buy the watch for elders, Apple Watch SE should be prefered over the Forerunner 255.
Garmin Forerunner 255 also has an incident detection feature. But, it is limited to specific activities alone. When a Forerunner 255 detects a hard fall, it sends in emergency notification to up to 3 designated emergency contacts. It shares the geo-location data of the wearer. But, a Forerunner 255 cannot call the emergency services to seek 911 kind of support.
Clearly, Apple Watch SE has a better incident detection and response program on the watch that a Forerunner 255.
Garmin Forerunner 255 has a Pulse Oxygenation sensor that tracks oxygen saturation levels in blood. You can take a spot reading of blood oxygenation levels. Or, you could choose to track blood oxygen in your sleep.
Apple Watch SE does not track blood oxygenation levels as it does not have the pulse oximeter sensor on the watch.
Running and Activity Tracking
Apple Watch SE tracks multiple activities like swimming etc. It does so as part of activity tracking module. Most basics of activity monitoring for swimming are in-built into the Apple Watch SE.

All these fitness activities are tracked as part of a training and activity monitoring suite on the Garmin Forerunner 255 watch.
