It seems that the rumors have been fulminant this time and the watch has been presented to us as we have seen it in the leaked captures. The clock itself it is a little bigger reaching 40 and 44mm so they are somewhat larger, 2mm compared to the previous versions.
The watches have a ceramic bottom to better capture the pulsations and obviously another improvement is the clock processor that has 64 bits and is up to two times faster than the previous ones Apple Watch Series 3.
The truth is that the work done on the screen is noticeable and it is that you can see much more information and they have a somewhat more rounded design so that it looks better aesthetically. It is true that the new watchface that they have shown us in the keynote they look great on that new screen.
In addition, the crown, the speaker have been improved and a single sensor is shown at the bottom of the clock that will be in charge of measuring our pulsations. The watch will continue to warn in cases of coronary arrhythmia and it is true that the back is made of ceramic. ECG directly from the crown of the Apple Watch Series 4, which means that by putting your finger on it the watch will be able to perform an electrocardiogram that we can store and take to the doctor. It seems that the improvements to the device are many and we will continue to see the news in the moments after when the keynote ends.
