Garmin Forerunner 970 / Apple Watch Ultra (49 mm, 1st generation)

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.

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

LTPO lets the refresh rate drop very low, so the screen can stay on without draining the battery. 2000 nits was twice as bright as any earlier Apple Watch display.

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.

Availability of the ECG and blood oxygen apps varies by country.

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 flat front crystal is protected by a raised titanium edge.

Availability of Ultra Wideband features varies by country.

The L5 signal helps separate signals reflected by tall buildings and trees; Apple called it the most accurate GPS of any Apple Watch at the time.

Apple points to the third-party Oceanic+ app for recreational scuba diving to 40 metres; the watch itself is not certified as a dive computer.

The siren plays two distinct patterns, one signalling distress and one mimicking SOS.

With cellular, the watch can make calls and get messages without the phone nearby; carrier support is required.

Runtime depends on display, workout and cellular use; using LTE away from the phone drains the battery noticeably faster.

Apple announced that this setting would arrive in software after launch, in autumn 2022; it extends runtime by taking some readings less often.

The watch can only be set up and used with an iPhone; it does not pair with Android phones.
