Glass and case—Sapphire 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.

Samsung
Processor and memory—Exynos W1000 (5-core, 3 nm); 2 GB RAM, 32 GB storage

32 GB of storage is enough to keep music and apps on the watch for phone-free runs.

Samsung
Battery and charging—435 mAh (typical); WPC-based fast wireless charging

The watch charges only wirelessly; it must align with Samsung’s charging puck, and some wireless chargers may not sit flat because of the band.

Samsung
Health features—Antioxidant 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
Location—L1 + L5 dual-frequency GPS (GPS, GLONASS, BeiDou, Galileo)

The L5 band helps reduce route drift caused by reflections among tall buildings and trees.

Samsung
Connectivity—Bluetooth 5.3, Wi-Fi 2.4 + 5 GHz, NFC; this model has no LTE (Bluetooth)

On the Bluetooth model calls and notifications work while connected to the phone; NFC contactless payments depend on country and bank.

Samsung
Durability—5ATM, IP68, MIL-STD-810H
