It has a 7.6" 1848x2448 (3,000 nits peak) 4:3 foldable LTPO Flex Titanium OLED, and the external display is a 5.5" 1248x1972 10:16 LTPO OLED.

Garmin launches the first microLED smartwatch, with a round 1.4" 4,500-nits display

Garmin launched the world's first microLED wearable, the Fenix 8 MicroLED smartwatch. It uses a 1.4" 454x454 round microLED display that offers a brightness of 4,500 nits. This is the world's brightest smartwatch, as OLED panels today achieve only 3,000 nits .
