Watch Series 3 - the third generation of smart watches from Apple. One of the most important innovations is the availability of a cellular communication module in hours, so you can receive calls and use the Internet without communicating with your iPhone. The processor in the clock is also new - the Apple S3, a more productive dual-core chip. The Bluetooth module has also been updated, now it's Apple W2, a chip developed by the company to improve the quality of wireless communication. Another innovation will be appreciated by athletes - in the hours there is a barometric altimeter that, coupled with GPS, can track not only your exact location, but also the heights and climbs that you overcome when jogging. The battery life has not changed compared to previous generations and is 18 hours.
