Citizen ECO-DRIVE Chronograph AT2140-55E Men's Watch

“Eco-Drive” refers to a watch mechanism that operates by converting light into electrical energy. It is equipped with a solar cell that generates electricity when exposed to light, powering the watch. Excess electrical energy is stored in a secondary battery.

It eliminates the need for regular battery replacements, does not contain harmful metals in the secondary battery used, and does not use harmful substances during the manufacturing process. As such, it receives high praise from an ecological standpoint and was the first watch to be certified as an “Eco Mark Product.” Recommended as a present or gift.

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device's requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
