SAMSUNG GALAXY WATCH 3 45MM

The Samsung Galaxy Watch 3’s 360 x 360-pixel screen is sharp, bright enough to see in direct sunlight, and always-on. The Galaxy Watch 3’s onboard GPS measured my daily course accurately enough (it's roughly 1.2 miles, depending on how many times the dog wants to go in circles).
