SpecificationApple Watch Series 11 (46 mm, GPS)Samsung Galaxy Watch6 Classic (47 mm)
Release year20252023
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		1.5-inch (37.3 mm) Super AMOLED, 480 × 480 pixels; full-colour Always On Display; sapphire crystal glass

According to Samsung, the display is larger than on the Watch4 Classic and the rotating bezel is 15% thinner. Sapphire crystal resists scratches; the bezel partly surrounds the edge of the screen.

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		—
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.
