More than just pretty face, the Citizen Eco-Drive Calibre 8700 stainless steel men's watch also has a perpetual calendar that automatically adjusts for odd and even months and leap years through 2100. It features a perfectly round silver-tone stainless steel watch case and bezel that's complemented by a supple black leather strap with crocodile-like texturing.
The silvery white dial background is accented by day-of-the-week and 24-hour subdials, as well as a mode subdial that displays the selected function (local time, calendar, alarm). It also offers luminous, black-outlined hands (with seconds hand), a date function at 4 o'clock, and Roman numeral dial markers. Other features includes a dual-time function for tracking a second time zone, scratch resistant mineral crystal with anti-reflective coating, and water resistance to 100 metres (330 feet).
This watch is powered by Citizen's unique Eco-Drive, which absorbs sunlight and any artificial light through the crystal and dial to recharge the watch continuously. With regular exposure to light, the Eco-Drive continuously recharges itself for a lifetime of use. This watch's Eco-Drive provides a 180-day power reserve, and it can be recharged with just 4 hours of exposure to light.

The company was established in 1924. The founding fathers selected the name Citizen so it would be "Close to the Hearts of People Everywhere" and soon after adopted the company’s formal name, Citizen Watch Company.
During the last seventy-five years Citizen has expanded its business throughout the world and has achieved recognition as the global brand. The past twenty-five year period has coincided with the company’s dramatic rise to its current position as the world’s largest watchmaker, a distinction Citizen has held every year since 1986.
Beyond sheer size, Citizen is also recognized as a worldwide leader in advanced technology. From the world’s slimmest LCD watch to the first voice recognition watch and the world’s first professional dive watch with an electronic depth sensor, Citizen’s record of "world’s firsts" is unmatched.
More recently, Citizen has staked out a new position as the leader in Ecologically Friendly timekeeping with its Eco-Drives watches that are light powered. With models ranging from dress models to sports models to professional dive watches, Citizen Eco-Drive runs continuously in any kind of natural or artificial light for a lifetime of use. Fueled by light, it never needs a battery. Eco-Drive Frequently Asked Questions (See the full Citizen Eco-Drive FAQ here) How can you tell if the Eco-Drive watch is getting enough light?
In normal use, the watch displays the time and the sweep-second hand moves in one second intervals. A very important feature of Eco-Drive is the Low Charge Warning Mode which as a result of low battery voltage, causes the second hand to jump two seconds at a time (while still keeping correct time). How long will an Eco-Drive watch run after it is fully charged?
If your watch is put away where no light is available to it while in a fully charged state, depending on the model, it will run for from 45 days to 5 years. How can the Eco-Drive watch be recharged?
Besides sunlight, it can be safely charged by exposing it to a fluorescent desk lamp, with the dial (face) up and within about 8 inches or an incandescent lamp (regular light bulb) no closer than 20 inches. Never use a halogen lamp since the heat generated by it can cause damage to your watch. The most efficient and the quickest is in direct bright sunlight (not windowsill) and never on the dashboard of a car.
