Samsung Galaxy Watch6 (40 mm) / Samsung Galaxy Watch6 Classic (47 mm)

The 44 mm model has a 1.5-inch, 480 × 480 display.

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.

According to Samsung, an 8-minute quick charge adds about 8 hours of use; charging is WPC-based wireless.

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.

ECG and blood pressure work through the Samsung Health Monitor app only in markets where they are approved; blood pressure needs calibration with a cuff every four weeks. Body composition should not be used by people with implanted devices such as pacemakers or during pregnancy.

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

5ATM means water resistance to 50 metres for up to 10 minutes; the watch is not suitable for diving or high-pressure water. IP68 covers 1.5 metres of fresh water for 30 minutes.

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.

Some features, such as the camera controller and health measurements, need a Galaxy phone.

Thickness is measured without the health sensors.

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.
