---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- Set contents: Main unit, box, instruction manual, warranty card included in the instruction manual Waterproof: 20 ATM Mobile Link function that enables functional linking via Bluetooth® communication with compatible smartphones Shock-resistant structure that is resistant to shocks and vibrations Hand retraction function temporarily retracts the hour and minute hands that overlap the LCD display, making it easier to read the displayed data.
