The Citizen Calibre 5700 stainless steel men's watch is loaded with style and powerful timekeeping features, with its one-second chronograph measuring up to 30 minutes. It's also 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. It has a 150-day power reserve and a low-charge indicator.
This watch has a large, round silver stainless steel watch case--which measures 41mm (1.61 inches) wide and 10mm (0.39 inches) deep--that's topped by highly polished bezel with tachymeter readings in black. The hunter green dial background is accented by silver tone subdials, luminous hands, and baton dial markers. Other features include a date display at 4 o'clock, scratch resistant mineral crystal with anti-reflective coating, and water resistance to 100 meters (330 feet). It's backed by Citizen's 5-year warranty (from original date of purchase).
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.
