LTE versions of Apple Watch Series 4 can be identified by the distinctive red circle on the digital crown (in place of the red dot from the Series 3). The watch now comes in 40 mm and 44 mm configurations in a variety of colors and materials. Internally, the watch features a newly-engineered digital crown with haptic feedback and an electrical heart sensor for additional readings on that ticker of yours. The battery has a slightly upgraded capacity. The watch now comes with an all ceramic and sapphire crystal back to enhance RF connectivity.
