This is a CASIO G-SHOCK MINI watch. I took it in for a battery replacement, but they said the LCD was broken, so they returned it without replacing the battery. The battery may not be dead. I haven't checked. For 2,000 yen, they said they would exchange it for a new one, although it's not a G-SHOCK. Please confirm this yourself if you choose to exchange it. I will extend it for shipping and make it the size of a Yu-Packet Post. Please consider this. Thank you for looking.
