The embodiment of the application provides a wearable device, which includes a body part and a wearing part. The body part includes a middle frame plate, a frame, a first radiator and a second radiator. The frame is connected to the periphery of the middle frame plate, and the frame includes a first frame body and a second frame body arranged at intervals. The first radiator is arranged on the first frame body, and is used for transmitting and receiving Wi-Fi signals. The second radiator is arranged on the second frame body, and is used for transmitting and receiving long-term evolution signals. The wearing part is detachably connected with the body part, and is provided with a third radiator used for transmitting and receiving Wi-Fi signals or GPS signals. Both the body part and the wearing part are equipped with the radiators capable of accessing a wireless communication network. When one of the first radiator and the third radiator is blocked, Wi-Fi signals can be transmitted and received through the other radiator. Thus, the performance of the wearable device in accessing a wireless local area network is improved. The embodiment of the application also provides a smart watch.
