This item was received about 7 or 8 years ago. I'm not interested in watches and don't know how to use them, so my child used it a little, but it has mostly been stored for a long time. It seems to have a battery, but detailed operational checks such as adjustments haven't been performed. The metal parts of the screws are tarnished. If you are knowledgeable about watches or understand the item's condition, please consider purchasing it.
