Samsung Galaxy Watch8 Classic (46 mm, Bluetooth) / Samsung Galaxy Watch6 Classic (47 mm)

It is sold in one size only.

Sapphire crystal is a cover material that resists scratches better than ordinary glass.

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.

The rotating bezel lets you scroll lists and apps without touching the screen; its position is read by a 3D Hall sensor found only on the Classic. Quick Button can be assigned to an app or function.

Samsung says its charge times were measured with a separately sold 25 W adapter.

Setup and use need an Android 12 or later phone with more than 1.5 GB of memory and Google Mobile Services.

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.

Health features are for general wellness and fitness, not medical diagnosis.

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.

The second frequency (L5) helps accuracy where signals bounce, such as among tall buildings or under trees.

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

5ATM suits surface water use such as swimming, not diving or high-speed water sports. Samsung says its MIL-STD-810H testing cycled the watch between –20 °C and 50 °C for 6 hours in total.

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.

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

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.

Thickness is measured without the health sensors.
