My child purchased this from a gachapon machine. They only used it for the desired color and then stored it long-term. It's considered a disposable watch. I'm not sure about the battery life, but it turns off automatically, so I think it drains slowly. I confirmed that the date and time were correct when I checked it. Purple digital display wristwatch, silicone band, one-button operation. - Color: Purple - Display: Digital - Band Material: Silicone - Button: One button to switch between time, seconds, and date. Thank you for looking.
