Release year20252024
Display1.47-inch Super AMOLED, 480 × 480; full-colour Always On Display

Always On Display keeps the watch face visible but shortens battery life; when off, the screen wakes on wrist raise.

Samsung		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
Glass and caseSapphire crystal glass; 43.7 × 46 × 8.6 mm (excluding health sensors)

Sapphire crystal resists scratches better than ordinary glass. The 8.6 mm thickness excludes the sensor bump on the back.

Health featuresAntioxidant Index (carotenoid measurement), Bedtime Guidance, Vascular Load, Running Coach

Antioxidant Index is measured by holding a fingertip on the sensor for about five seconds; Vascular Load needs the watch to be worn to sleep on at least 3 of the last 14 days. These are wellness indicators, not medical diagnoses.

Samsung		Sleep apnea detection; Energy Score; AGEs Index (Labs, experimental)

Energy Score turns sleep, activity and heart data into a daily readiness score; AGEs Index is experimental and not for diagnosis.

Samsung
