Garmin Forerunner 970 / Apple Watch Series 10 (46 mm, GPS, aluminium)

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 aluminium version uses Ion-X glass; the titanium versions have sapphire crystal.

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

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

Up to 2000 nits and down to 1 nit. Apple says the wide-angle OLED looks up to 40% brighter when viewed at an angle, making the watch easier to read without raising the wrist.

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.

The electrical sensor enables ECG recordings and the optical sensor continuous heart rate. Availability of health features varies by country.

Suitable for shallow-water activities such as swimming, not for scuba diving or high-velocity water sports. The depth gauge is for snorkelling down to 6 metres.

This version has no cellular connection, so calls and data away from the phone need Wi-Fi. Location uses only the L1 band; there is no dual-frequency GPS.

Fast charging uses the included magnetic fast charger to USB-C cable; the adapter is sold separately.

An iPhone is required for setup and use; it does not work with Android phones.
