This is a CASIO Wave Ceptor Multi Band 6. It's a radio-controlled, solar-powered watch. The original box and extra links are all included. It's still within the warranty period as it hasn't been a year since purchase. I bought it in Yurakucho, Tokyo. It's great that you can easily add or remove links yourself. I've only worn it a few times, so it's like new. I will brush and clean it before shipping. Please consider it.
