Thank you for viewing. Please read the profile if you are considering purchasing. Also, as this is a defective item, please be sure to read the description. By applying for purchase, you are deemed to have agreed to the condition. This is a Casio men's watch, OCEANUS (Oceanus) Manta OCW-S3000. The battery is solar-powered. I purchased this a few years ago and used it almost every day. Due to button sticking, functions such as the stopwatch cannot be used. The sticking has been present since the time of purchase. If you wish to repair the buttons, please do so at your own expense. The watch functions perfectly as a timepiece. After purchase, I had the buckle replaced by the manufacturer. There are scratches and dirt from use. Items to be sent: Watch body, case, cushion, instruction manual, warranty (expired), and extra links for the band. We are looking forward to your purchase if you understand that this is a used item!
