Samsung Galaxy Watch8 44 mm Bluetooth (SM-L330) / Samsung Galaxy Watch6 Classic (47 mm)

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

According to Samsung, the display is larger than on the Watch4 Classic and the rotating bezel is 15% thinner. Sapphire crystal resists scratches; the bezel partly surrounds the edge of the screen.

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.

Samsung’s fast-charge testing used the magnetic fast-charging cable and a separately sold 25 W adapter. Battery life varies with network, usage and watch face.

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

Bioelectrical impedance analysis passes a weak current through the body when two fingers rest on the buttons to estimate muscle, fat and water; it should not be used with a pacemaker or during pregnancy. ECG and blood pressure work only in approved markets through Samsung Health Monitor.

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.

LTE is only on the LTE version; on the Bluetooth version internet and notifications come through the paired phone.

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.

5ATM corresponds to 50 metres for 10 minutes; it is not suitable for diving or high-pressure water. IP68 covers 1.5 metres in fresh water for 30 minutes.

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.

Turning the bezel moves between notifications and tiles without touching the screen; its position is sensed by a 3D Hall sensor.

Setup needs a phone with Google Mobile Services, Android 10 or later and more than 1.5 GB of memory; it does not work with an iPhone.

Thickness is measured without the health sensors.
