Samsung Galaxy Watch6 Classic (47 mm) / Samsung Galaxy Watch5 (40 mm, Bluetooth)

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 is a glass material that strongly resists scratching. The 44 mm version has a 1.4-inch, 450 × 450 screen.

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.

WPC is the body behind the Qi wireless charging standard. The 44 mm version has a 410 mAh battery.

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.

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 electrical heart signal is used for ECG and bioelectrical impedance for body composition estimates; availability of these features varies by country.

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

This version has no LTE; the LTE version is sold separately.

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.

5ATM suits shallow-water activities such as swimming, not diving.

Thickness is measured without the health sensors.

The watch works with phones running Android 8.0 or later with more than 1.5 GB of RAM; it cannot be used with an iPhone.
