The Citizen Men's Eco-Drive Strap Sport Watch has been perfected to suit both the professional man and the outdoorsman. This solar-powered Eco-Drive watch never needs a battery and remains charged for months at a time, even in the dark. Distinguished by rich black tones and chronograph technology, this watch's circular dial features three black subdials with sweeping hands over a striking black background. Textured with a grooved pattern, this background catches the light along with its overlaid frame of luminescent silver-tone bar hour markers and easy-to-read stick second markers. A large date window is perched at the four o'clock for at-a-glance reference, while the outermost dial is constructed with a tachymeter rim for computing speed (based on travel time) and distance (based on speed). This impressive dial is held by a silver-tone stainless steel case and bezel. And if you like to time short events, you'll be glad to note that the bezel is etched with Arabic second indexes in intervals of fifteen, as well as notched second markers along the first quarter-hour. A fine black leather band fastens this watch, featuring a crocodile pattern and a handy buckle clasp. Boasting a durable mineral window and the reliability of Japanese-quartz movement, this smart, distinctive timepiece is water resistant to 330 feet (100 M).
