While the Apple Watch 5 Series is Apple’s latest smart watch, the Series 3 is a cheaper option. The Apple Watch 3 Series is available in two sizes, 38 and 42 mm, and is slightly smaller than the 40 and 44 mm Series 5 models; however, it is slightly thicker and, unlike the latest model, lacks the ability to monitor the ECG.
The Series 3 is not much weaker than the 5 Series. This smartwatch is equipped with the ability to monitor heart rate, GPS and 8 GB of internal memory to store songs and is resistant to water and dust. It also benefits from many of the Series 5 software features in the Watch OS S6 operating system.
