Samsung - Galaxy Watch 9 - Black , 40mm

The Galaxy Watch 9 tracks heart rate, sleep stages, blood oxygen, and daily activity around the clock, syncing everything to Samsung Health for long-term trends and coaching insights. A bright always-on display keeps the time and key stats visible at a glance, and built-in GPS maps outdoor runs, walks, and rides without needing a paired phone nearby. Samsung's BioActive sensor combines several health readings into one chip for faster, more accurate measurements, and the watch supports guided breathing, sleep coaching, and workout detection across dozens of exercise types. Wireless charging tops the battery off quickly between wears, and the watch pairs with both Android notifications and quick-reply tools for a connected experience on the wrist.
