I purchased this watch at a watch store for approximately 15,000 yen. I really liked it, but I no longer have the opportunity to use it, so I am putting it up for sale. There are no instructions or box. It is working. I replaced the battery once, but I don't know how long it will last. I have confirmed that each button responds normally and that the time can be changed. The light also works. You can find instructions on how to change the time by searching for BABY-G "5257". As you can see in the photos, there are some minor scratches. Please understand that this is a used item and consider purchasing it. *We do not accept requests for exclusive sales or holds.
