Apple Watch Series 4 "40 mm" Cellular(US/CA) Specs

Apple Watch Series 4 - MTUD2LL/A - Watch4,3 - A1975

About This Watch

The Apple Watch Series 4 is very similar to previous devices in its line-up but features larger screens as well as a few upgraded components which improve the functionality and features of the watch. The Series 4 has larger screen sizes of 40 mm and 44 mm which allows for more internal space inside the watch and more screen area for apps to use. This model has cellular capabilities allowing it function without being tethered to an iPhone.

Apple decided to focus on health with this device. This was emphasised by the new accelerometer and gyroscope which are used to detect when a user has a fall. The heart rate monitor already tracks sudden spikes or irregular patterns and warns users of the risk of a stroke. Apple introduced an electrical heart sensor(ECG) into the Series 4 watch. This single pulse electrical heart sensor is able to detect signs of atrial fibrillation and alter the user.
