The Samsung Galaxy Watch 4 (stylized as Samsung Galaxy Watch4) is a smartwatch developed and marketed by Samsung Electronics. It is the first Samsung watch to run Google's Wear OS since the Gear Live, and the first watch to run Wear OS 3, co-developed by Samsung and Google. The device largely followed the design language of the preceding Galaxy Watch Active 2 and Galaxy Watch 3, but including all new software. The watch also included EKG, body compositional analysis, and blood pressure monitoring via the Samsung BioActive sensor. It was announced on August 11, 2021, at Samsung's Galaxy Unpacked event alongside the Galaxy Z Fold 3, Galaxy Z Flip 3 and Galaxy Buds 2. The watch was released worldwide on August 27, 2021.
The Galaxy Watch 4 was succeeded by the Galaxy Watch 5 on August 10, 2022, and had the FE-based model on June 13, 2024.
