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 40 mm configurations for the market in Canada and the US can be further identified by the model number A1975 visible in the grove when the strap is removed. 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.
