Samsung Galaxy Watch8 Classic (46 mm, Bluetooth) / Garmin Forerunner 970

It is sold in one size only.

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

Garmin calls it its brightest AMOLED yet but publishes no nit figure. Touch and buttons can be used together.

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.

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

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

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.

The numbers correspond to colour options; the US page does not map each number to a colour. The page image belongs to 010-02969-01, Whitestone case with Whitestone/Amp Yellow band.

The Forerunner 965 used Gorilla Glass 3 DX; sapphire is more scratch-resistant.

Red light disturbs night vision less in the dark.

The ECG app screens for signs of atrial fibrillation; it is for adults 22 and over and is not available in every region.

Running tolerance suggests a weekly maximum distance. Running economy and step speed loss need the separately sold HRM 600 chest strap.

With activity tracking, notifications and wrist heart rate; Garmin notes active features affect the result.

With music the figures are 14, 13 and 12 hours. Multi-band uses several satellite frequencies to improve accuracy in cities and valleys at the cost of more power.

Used for music and maps; this is not RAM.

Withstands pressure equivalent to 50 m depth; it is not a dive watch.

13.56 MHz is the NFC band used for contactless payments.
