Purchase date and price unknown. Operation not confirmed. It is also unknown whether it will work after replacing the battery. I used it, but it has been stored without use for a while. There are fine scratches and dirt. The band is relatively clean. There is no box or instruction manual, so I cannot provide detailed explanations. Please check the images. CASIO G-SHOCK GAUSSMAN.
