CASIO Standard Moon Phase Model Number: MTP-M305L-1A2V Purchased about six months ago, used about three times a month. There are some light scratches from use, but overall, I think it's in good condition. I replaced the original leather strap because I didn't like it (it felt cheap) with a rubber strap. The rubber strap is compatible with quick levers, which are often used in smartwatches, so it can be easily replaced without tools. It's also magnetic, so it's easy to put on and take off the watch. Operation has been confirmed, but since it is a used item, please refrain from purchasing if you are concerned about minor details. I will pack it carefully and ship it. Thank you.
