"The Timex Expedition Field Chrono draws style motivation from vintage military watches. The distinct dial features characters in increments of five as much as 60 and 3 sub-dials that track minutes, seconds, and 1/20 of a 2nd for as much as Thirty Minutes. A simple to operate date window lies at 4 o'clock. With the Quick Date function, you can set the date on the watch without turning the crown for each 24-hour duration. Just pull the stem midway out, and turn till desired date is reached. It also offers water resistance to 330 feet (100 meters) and a durable leather strap. The Indiglo night-light consistently lights the surface of the watch dial using trademarked blue electroluminescent lighting technology. It uses less battery power than most other watch illumination systems, enabling your watch battery to last longer."
