Thoroughly modern with unrelenting style, the ultra-light, ultra-durable Citizen BL5210-58E titanium men's watch is packed with powerful chronograph timekeeping features. Titanium is nearly 50 percent lighter than steel, but 30 percent stronger. It's also particularly resistant to salt water corrosion. This watch is also powered by Citizen's unique Eco-Drive, which absorbs sunlight and any artifical 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.
The silver stainless steel watch case features a Tonneau design, with its rounded barrel-like convex sides, amd a black dial background with luminous hands (and a second hand). The chronograph's three subdials measures 1/20th of second intervals up to 60-minutes, has 12-hour and alarm registers. The watch also has a perpetual calendar that automatically adjusts for odd and even months and leap years through 2100. The case flows seamlessly into the slightly tapered bracelet band, which is composed of both brushed and polished silver stainless steel pieces. It's joined by a push-button butterfly clasp. Other features include Japanese quartz movement, water resistance to 100 meters (330 feet), and Citizen's 5-year warranty.
Eco-Drive Frequently Asked Questions 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.
