This is the analog version 120 of the MRG, an early model from CASIO. It's quite old, but I've replaced the battery once. The backlight also works. Since it's quartz, you'll need to set the time yourself. There's no box or extra links. I haven't worn it recently, so I'm offering it to someone who will. My wrist size is about 19cm, measured by a novice. The resin cover on the back is missing. It's made of stainless steel.
