The 'WLAN only' statement means that this version of the watch is equipped with a Wi-Fi connection, but it doesn't specify whether it excludes other types of connectivity such as Bluetooth. However, given that most smartwatches include Bluetooth connectivity to connect to mobile devices, it is likely that this watch also has this functionality. The 'WLAN only' statement could be used to emphasise the watch's ability to connect directly to a Wi-Fi network without going through a smartphone, which is useful for software updates or downloading music.
