I don't plan to lower the price, so please buy it while the battery still works! CASIO It seems like even children can use it. Please inquire about the length, etc. Opened for photography. The original battery has a 7-year lifespan, but I don't know how long it's been used. It's currently working normally. There is a warranty card, but no stamp, so there is no warranty. There are sticker removal marks on the box. This is a lightweight, thin digital LCD model. It has convenient functions such as date and day display, alarm, and stopwatch. Also listed elsewhere, so please be sure to check stock before purchasing. Also selling a different color: blue. Children's wristwatch
