Release year20252024
DisplayAlways-On Retina, LTPO3 OLED (wide-angle OLED); 416 × 496 pixels, 1196 mm²; 326 ppi; up to 2,000 nits, 1 nit minimum

Because LTPO can drop the refresh rate very low, the display stays dimly on even with the wrist down. Wide-angle OLED is used to reduce brightness loss when the screen is viewed from the side.

Apple		Super AMOLED; 480 × 480 (about 327–330 ppi); 2000 nits

The 2000-nit peak helps readability in sunlight; using the always-on display shortens battery life.

Samsung
Front glassIon-X glass with ceramic coating

According to Apple, the coating gives twice the scratch resistance of the Series 10 Ion-X glass. Titanium cases use sapphire crystal.

Health sensorsElectrical heart sensor; third-generation optical heart sensor; blood oxygen sensor; temperature sensor

The electrical sensor records a single-lead ECG with the ECG app. According to Apple, blood oxygen and wrist temperature are for general wellness, not medical use.

Apple		BioActive sensor: heart rate, irregular heart rhythm notification (IHRN), ECG, blood pressure, BIA body composition; continuous SpO2; skin temperature

Availability of ECG and blood pressure depends on country and paired phone; blood pressure measurement is not offered in the US.

Samsung
Health notificationsHypertension notifications; sleep apnea notifications; sleep score and sleep stages; irregular rhythm and high/low heart rate notifications

Hypertension notifications do not measure blood pressure; they alert when patterns in the optical sensor data suggest high blood pressure. According to Apple, they are not for users under 22, those already diagnosed with hypertension or pregnant users.
