And thanks to Citizen's amazing Eco-Drive technology, you don't even have to worry about changing the battery. These watches will run virtually forever on the power of light. The watches have a 180 day (6 month) power reserve. Even if you only wear the watch on weekends, the watch will be running and the time will be perfect whenever you pick up the watch.

Four models are available in this series. Pictured above are the classic Infantry Model and the Chronograph, stop watch, model. Pictured to the right is the new Officer's Field Watch model, a larger watch with oversized numerals. All three watches have a washable canvas strap. And all four have a luminous dial for good night time visibility. Regardless of which watch you chose, all have the same great features.
