Samsung Galaxy Watch8 44 mm Bluetooth (SM-L330) / Apple Watch SE (2nd generation, 44 mm)

Always On Display keeps the watch face visible but shortens battery life; when off, the screen wakes on wrist raise.

SE has no always-on mode; the screen wakes when you raise your wrist. Ion-X is strengthened glass and is not as scratch-resistant as sapphire.

Sapphire crystal resists scratches better than ordinary glass. The 8.6 mm thickness excludes the sensor bump on the back.

32 GB of storage is enough to keep music and apps on the watch for phone-free runs.

The watch charges only wirelessly; it must align with Samsung’s charging puck, and some wireless chargers may not sit flat because of the band.

The electrical heart signal enables ECG and bioelectrical impedance enables body composition readings. ECG and blood pressure need a Samsung phone and country approval.

The high-g accelerometer and gyroscope are used for Crash Detection. ECG, blood oxygen and temperature sensors are not included on this model.

Antioxidant Index is measured by holding a fingertip on the sensor for about five seconds; Vascular Load needs the watch to be worn to sleep on at least 3 of the last 14 days. These are wellness indicators, not medical diagnoses.

The L5 band helps reduce route drift caused by reflections among tall buildings and trees.

On the Bluetooth model calls and notifications work while connected to the phone; NFC contactless payments depend on country and bank.

5ATM means water resistance suitable for swimming, not diving or high-speed water sports. MIL-STD-810H refers to selected environmental tests from the military standard and is no guarantee against impacts.

Gemini can act in Samsung Health, Calendar and Clock via voice; availability varies by device, language and country.

It cannot be used with an iPhone.

The watch can only be set up and used with an iPhone; it does not work with Android phones.

Weight is for the case only and rises with the band. The 44 mm case fits 140–245 mm wrists.

Storage holds music, podcasts and apps and cannot be expanded.

Crash Detection can call emergency services after a severe car crash. Emergency SOS needs a cellular connection or Wi-Fi calling with internet access from the watch or a nearby iPhone.

Apple measures 18 hours with 90 time checks, 90 notifications, 45 minutes of app use and a 60-minute workout with music; on the cellular model, 4 of those hours are on LTE. Longer GPS workouts shorten it.

Suitable for swimming, but not for scuba diving, water skiing or high-velocity water sports.

The cellular model can make calls and use data without your iPhone nearby; carrier support is required.
