Casio makes a whole range of clocks, but only a couple are of much interest to G-Shock fans. The most notable models are the classic GQ-200 and the new GQ-1000. These aren't too common in the US, but you can find them in Japan quite easily.

The first is the GQ-200 G-Shock Muscle Clock. This one is no longer in production, but it can be picked up on eBay for tidy sum. It's the only true G-Shock clock ever produced, but it's not the best looking.

The GQ-1000 is a newer clock that appeals to G-Shock fans. It comes in silver and black variations. The retail price for these is only around $55 USD, but they've been popping up on ebay.com for over three times the retail price.
