If you're familiar with the original Galaxy Watch, the look of the Active won't come as too much of a surprise. Its round watch face looks more like a traditional timepiece than the square Apple Watch. Both rely on the touchscreen and physical buttons for navigation which is fairly intuitive. Unfortunately the Active misses out on the rotating bezel from the original Galaxy Watch that we loved and that gave it a more premium look.

Apple gives you two sizes to choose from with the watch face: either a 40 or 44 millimeter while the Galaxy Watch Active has a single 39.5mm size. Each screen is easy enough to see in bright, outdoor situations, but the Apple Watch has thinner bezels so you can see more of the screen on the surface of the watch face and the thicker straps make it look slightly more elegant.
