Please consider purchasing with confidence. ~Product condition~ Working condition It's solar-powered, so no battery replacement is needed. It has other functions like day and date, but these have not been tested. The backlight works. There are small scratches on the crystal. The band also shows signs of use, but I believe it won't be too noticeable for those who understand pre-owned items. ~Specifications~ Quartz ~Size~ Please check the images. ~Brand~ CASIO G-SHOCK Model Number: MTG-900 Before listing, I have confirmed that the watch is in working order. The time has not been set, so please adjust it after purchase. Additional functions such as the chronograph have only undergone basic operation checks. Detailed functions such as alarms, calendars, and lights have not been fully tested for all operations. Regardless of whether the watch is rechargeable, automatic, or battery-powered, I cannot determine the condition of internal consumable parts or the remaining battery life. All buttons have been confirmed to be pressable. Long-term accuracy measurements and professional inspections have not been performed. The item will be sold as-is, and I hope to pass it on to someone who understands this. If you have any concerns, please feel free to ask questions before purchasing.
