Can solar watches be used, solar and photoelectric watches

Solar watches with battery-related issues".

What is a solar watch?

The text board is inlaid with a solar panel, which receives light and converts it into electricity, which is stored in the secondary battery and becomes the power source of the watch.

Since the secondary battery stores power, the watch can still be rotated even when the solar battery is not generating electricity.

Doesn't it matter if direct sunlight is also available?

In general, direct light is the most efficient way to charge, however, be careful not to leave the watch in extreme heat. This can cause damage to the components. The same is true when charging with electric lights.

Do I need sunlight to charge?

Indoor light (lamps and lamps) can be charged. The charging time varies depending on the intensity of the light, so please refer to the manual.

Do I have to charge it every day?

It can be used for 5 months when it is full and there is no light (no charging), [with an average of 10 seconds of electronic pronunciation per day and one radio wave reception].

However, when there is no charging, the solar charging system of the watch is not the same as the charging system of the mobile phone when there is electricity, and it will not be fully charged in a short time. So please refer to the manual, do not leave the watch in a state of undercharging, it is very important to charge it frequently.

Can I charge it on my wrist?

If it is outdoors on a sunny day, or bright indoors, it can be charged.

However, it is necessary to prevent clothing (sleeves of jackets or jackets, etc.) from covering the watch and not charging it.

What is the lifespan of solar cells and secondary batteries?

Basically, in actual use, it can be ensured that there will be no longevity problems.

Solar cells and secondary batteries will age to some extent, but there is no problem at all after 10 years of use.

However, watch dials, display plates, and waterproof seals need to be serviced regularly and replaced as needed.

The rechargeable battery used in Eco-Drive watches is a long-life rechargeable battery (with a life span of about 20 years), and an amorphous solar cell that converts a variety of light energy into electrical energy, and has a lifespan of more than 20 years without problems during use.

There is no difference. Light energy meters, also known as solar watches, can move around as long as the surface is exposed to light, and it can last for a period of time in places where there is no light.

An Eco-Drive watch, or ecology-drive in English, is a watch that has a built-in system that converts light energy into electrical energy. By using batteries that do not have to be discarded, it is a truly eco-friendly product that can save limited global resources and reduce pollution.

In 1996, it was recognized as the first "Eco-Product Mark" in the watch industry in Japan. In 2001, it obtained the first "Environmental Labeling Product" certification in China's watch industry. Not only does it realize that "watches can be driven by light", but also rechargeable batteries no longer use harmful metals such as mercury and cadmium.

In addition, the manufacture of product materials also avoids the use of fluorine and other harmful substances, and has passed various strict standards.
