The above background uses the various power generation methods of the present invention to generate electricity in a timely manner. There are several methods, which are described as follows: First, a solar device is used on the surface of the watch case, wherein the solar device is composed of a solar power generation panel, which converts light into voltage to form a solar cell, which is introduced into the smart watch through leads; strong light can replace sunlight when necessary.

[0003] Second, use the solar device on the surface of the strap, where the solar device is composed of a solar panel that converts light into voltage to form a solar cell, which is introduced into the strap of the smart watch through a lead wire; there is a rechargeable battery in the strap to store electricity, and when necessary, the voltage output port of the battery strap is connected to the charging port of the main wearable device with a wire. When necessary, strong light can replace sunlight. The main wearable device has a connecting wire that can be connected to the battery strap and use the power supply of the battery strap.

It is also possible that the power is used up and there is no opportunity to charge when it is urgently needed.

[0005] Sometimes, a wearable device needs to be waterproof up to 50 meters underwater. There are many types of wearable devices to be used, and it is impossible to develop a waterproof design mold for each type, which will cost a huge amount of mold fees. The present invention has a waterproof effect of 50 meters underwater. The original wearable device can be removed and placed in the main wearable device, so that the wearable device can be operated underwater.
