【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.

The brand logo is engraved on the crown, making it an exquisite piece with thorough attention to quality. The mechanical movement of the hands has a romance that is not found in the 1-second movement. When fully charged, it will run for about 41 hours (if you wear it, the pendulum movement will further extend the drive time).
