Citizen celebrates the 20th anniversary of its professional-quality Aqualand diving watch with this special analog/digital Eco-Drive edition, which features a backlight and dive log memory. It offers water resistance to 200 meters (660 feet), suitable for scuba diving. And it's powered by Citizen's exclusive Eco-Drive technology, which charges the battery from both indoor and outdoor light. It has a wealth of dive measurement functions, including:

• Depth display to 300 feet in digital format, with current and maximum displays
• Measurement of depth and time of dive
• Current and lowest water temperature display
• Surface interval measurement
• Dive log memory for up to 20 dives

Other timing functions include world time in 42 cities, 29 time zones, ability to track time in two different time zones, three alarms, 12/24-hour time display, and three alarms. Other features include a comfortable rubber strap, electro-luminescent backlighting for low-light visibility, screw-back case, screw-down crown, and a scratch resistant mineral crystal with anti-reflective coating.

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 1.5 hours of exposure to light.

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.

Warranty

About Citizen
One of the world's largest watch makers, the Citizen Watch Company was founded in 1924 in Japan from its beginnings as the Shokosha Watch Research Institute. The first watch released by the company was named "CITIZEN" and its name was selected so that it would be "close to the hearts of people everywhere." Today, Citizen is recognized as a worldwide leader in advanced timepiece technology, from the world's slimmest LCD watch to the first voice recognition watch to the world's first professional dive watch with an electronic depth sensor. Citizen was also the first to sell watches made with titanium in the world, which is not only light and durable but also non-allergenic (as stainless steel can be to some wearers). Most recently, Citizen has released watches powered by its Eco-Drive, which runs continuously in any kind of natural light or artificial light for a lifetime of use without changing a battery.

The Citizen Watch Brand

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.
