In parallel with the release of the iPhone Xs in the fall of 2018, Apple introduced the fourth version of the Apple Watch smartwatch. This time, the changes affected both the appearance, the filling, and the functionality of the watch, which delighted many fans of the brand. Firstly, the watch has become bigger. The 38 and 42-inch models were replaced by versions with body diagonals of 40 and 44 mm. Accordingly, the diagonal of the display has grown.


Secondly, important health monitoring functions have been added, after all, it's not for nothing that Apple positioned them as an important tool in this regard. To begin with, we note the appearance of the long-awaited ECG sensor, with which the user can take heart readings directly from the wrist and receive recommendations to consult a doctor in case of improper heart function. For example, arrhythmias. It is impossible to ignore the new function of tracking the fall of a person. If the watch decides that the user has fallen, they will offer to call an ambulance. If there is a fainting and the owner does not respond within a minute, they will call an ambulance on their own.

Inside the Apple Watch 4, a brand new Apple S4 processor is "rumbling", which, according to the company, has become twice as fast. The speaker and microphone were pumped, which some owners complained about. The microphone has become more sensitive, and the speaker, accordingly, louder. The Digital Crown wheel has added a feedback option. As for the operating system and built-in applications, new training modes have been added to the "four", as well as the opportunity to compete with other Apple Watch owners.

The model range did not bring any surprises in comparison with the third generation. Several diverse versions of the Apple Watch 4 with 40- and 44-millimetre cases have gone on sale. They include classic aluminium watches and steel versions, watches from Nike with a perforated strap and a metal case and a modification from the French fashion house Hermes with a designer dial and a leather strap. As in the case of the third generation, models with a telephone module are marked Cellular or CELL.
