It's broken. There are stains. The belt is peeling. Purchased about 20 years ago. (Tick-tock) I think it was a foreign model. I had the battery replaced at the store where I bought it once. The battery died again, and I tried to replace it myself by opening the screws, but I didn't understand anything, so I closed it back up. I would appreciate it if someone understands this condition. #GShock #Casio #CASIO
