Wristwatch

I purchased this online for my child (¥1980) but haven't had a chance to use it, so I'm listing it for sale.

The analog hands are working without any issues.
I'm unsure how to adjust the digital display, so I haven't been able to confirm its operation.

I'm selling it at a lower price because of this, so I'd be happy to sell it to someone who understands.

It will be sold as-is, so please no returns.
Thank you for your understanding.
