【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.

It also features a large three-tier display panel that allows you to check split, lap, total time, or running lap time at the same time, as well as a memory function for storing measurement data. It is water resistant to 10 ATM, so you can use it with confidence during rainy weather or during sports where you are likely to get splashed. (Perfect for swimming, rowing, and water sports)
