Samsung Galaxy Watch8 Classic (46 mm, Bluetooth) / Google Pixel Watch 4 (41 mm, Wi-Fi)

It is sold in one size only.

The 45 mm model weighs 36.7 g.

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

GIGAZINE gives the 41 mm model's resolution as 426 × 426.

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.

The co-processor handles notifications and sensor work while the screen is off without waking the main processor, saving battery.

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

The 45 mm model has a 455 mAh battery and up to 40 hours with the always-on display.

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

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

ECG and some health features may be limited by country; readings are not a medical diagnosis.

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

This entry covers the Wi-Fi model; LTE and UMTS cellular connectivity is only on the LTE model.

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.

5 ATM suits shallow-water activities like swimming, not diving or high-speed water sports.

The ability to drop to 1 Hz reduces the battery cost of the always-on display.

The watch sits in a new side-mounted dock; earlier Pixel Watch chargers do not fit this model.

Some features depend on the phone's Android version and the Pixel Watch app.
