The watch is commonly known as "Citizen Eco-Drive".

The Citizen Eco-Drive watch typically doesn't need recharging, as it's powered by light. The watch can recharge itself as long as it's regularly exposed to light. However, if the watch remains in the dark for extended periods, the energy source may be depleted. In this case, the watch can run for up to six months without light before needing to be recharged. Regular exposure to light is important to ensure optimal performance.

The Citizen watch's Eco-Drive system works by converting light energy into electrical energy. The watch is equipped with a solar cell module that uses both sunlight and artificial light to charge the battery. This technology allows the watch to run continuously as long as it is exposed to light. However, if the watch remains without light for an extended period, it can switch to energy-saving mode. Typically, a fully charged Eco-Drive watch can operate for up to six months without sunlight before needing to be recharged.

The Citizen Eco-Drive watch is charged by a special solar cell integrated into the dial. This cell converts light energy, from both natural and artificial light, into electrical energy, which is then stored in a rechargeable battery. The most effective light sources for charging are direct sunlight and bright artificial light, such as LED or fluorescent lamps. The more light the watch receives, the faster the battery charges. It is important to expose the watch to light regularly to ensure optimal performance.

To maximize the lifespan and functionality of your Citizen Eco-Drive watch, you should follow some important care tips. First, it's important to regularly expose the watch to light, as the Eco-Drive system relies on sunlight or artificial light to charge the battery. Avoid storing the watch in dark environments for extended periods.

Clean the watch regularly with a soft, dry cloth to remove dirt and dust. If necessary, you can use a slightly damp cloth to remove stubborn stains, but be careful not to let water get inside the watch, especially if it is not waterproof.

Protect your watch from extreme temperatures, strong magnetic fields, and chemical substances, as these can impair its functionality. If your watch is waterproof, regularly check the seals and have them replaced by a professional if necessary.

Have your watch checked by an authorized service center every few years to ensure all functions are working properly and the watch is well-maintained. By following these simple care instructions, you can significantly extend the lifespan of your Citizen Eco-Drive watch.
