Well, I don't know the model number; it is not printed on the watch and I tossed the box three years ago. But, it says "Expedition" right there on the top of the watch face together with " Water 100m Resistant". On the bottom of the face is a button with "Indiglow" printed on it and when I push the button, the LCD screen lights up with a blue-green color. My granddaughter loves the light and keeps pushing the button; perhaps that's why I had to replace the battery. The light and the chronometer are the main reasons I got this particular watch although having it tell time and the date are also a plus. The watch is pretty scratched up and scuzzy by now and the leather watch band has a peculiar odor to it but otherwise, it's as good as new. <img src="/forums/images/graemlins/grin.gif" alt="" />
