CASIO G-SHOCK GST-W310 This watch is solar-powered. No box or accessories are included. I received this as a gift, so I don't know the period of use or frequency of use. I'm also unsure if the battery is degraded, but it's currently working without any problems. -Additional Information- After leaving it in a place indoors where light doesn't reach, it ran out of charge within a few days. It seems the battery is degraded. There are noticeable stains and scratches on the back of the band. Please consider this item with the understanding that it is a used item and its condition cannot be guaranteed. I will answer questions as much as possible, so please contact me if you have any concerns. It will be shipped via Yu-Packet Post.
