Galaxy Active 2

The Active 2 has a bright, circular AMOLED touchscreen, comes in two sizes (40mm and 44mm) and has a Bluetooth or LTE option. It has improved heart-rate tracking over the original Galaxy Watch Active ($139 at Amazon) and is compatible with Android and iOS, although you don’t get all the features if you pair with an iPhone.
