Thank you for viewing. CASIO G-SHOCK Radio Solar GW-7900B Casio G-Shock The watch is running, but I am unsure if the time is accurate. It was synchronized with other watches I own. I am sorry, but I cannot confirm if all functions are working. Please be aware of this beforehand. Size: Please check the images. I purchased this several years ago. There are scratches, minor imperfections, and dirt. In my subjective opinion, it appears to be in relatively good condition overall. To ship via Yu-Packet Post, the band may be extended for shipping. Please be aware of this beforehand. Yu-Yu Mercari delivery may be changed to Raku-Raku Mercari delivery. I hope someone can make use of this. Thank you.
