Samsung announced the Galaxy Watch 5 and Watch 5 Pro on Wednesday, giving its round, semi-rotating Wear OS watches new looks, a tougher screen material, and—for reasons the company can only vaguely explain—an infrared temperature sensor.

Neither the $280 Watch 5, available in 40 or 44 mm sizes, nor the 44 mm $450 Watch 5 Pro has a physically rotating bezel, a distinguishing Galaxy Watch feature that was limited in the last generation to the higher-end Watch 4 "Classic" (which is still available). Instead, both models have capacitive touch bezels, so you can run your finger around the edge to scroll.
