Therefore, the presence of wireless connections is essential for the proper functioning of the watch.

There are several Bluetooth technologies, more or less dated, and it is therefore important to assess which of them are supported by the best connected watch. Additionally, many models have WiFi connectivity, which is useful if you have a wireless home network.
Battery life is a key aspect to consider when purchasing. On average, connected watches have an autonomy of between 24 and 48 hours; some of the best smartwatches have a battery life of 3 or 4 days. However, a lot also depends on the intensity and type of use of the watch. The duration of the recharge is also important, which in most cases is around 2-3 hours.

In addition, some smartwatches are resistant to greater depths. To understand how far it is possible to go, the manufacturer will specify the so-called atmospheres (GAB).
