About the Samsung Galaxy Watch8 40mm
Galaxy Watch8 is Samsung's mainstream Wear OS smartwatch, now thinner than the previous generation with a cushion-shaped design. The 40 mm model suits smaller wrists. It runs on the Exynos W1000 with 32GB of storage and launched on Wear OS 6 with One UI 8 Watch, which brings Gemini voice assistance to the wrist.
Samsung's BioActive sensor tracks heart rate, ECG and body composition. New health features include an Antioxidant Index, checked by placing a thumb on the sensor, Bedtime Guidance based on your sleep pattern, and a Running Coach. The 40 mm model has a 325 mAh battery, and the watch is rated 5ATM and IP68 with MIL-STD-810H durability testing.
