If you crave function as well as sport style on your professional diver watch, you'll love the Perpetual Calendar.

Amazon.com Product Description:
Providing a powerfully masculine style and precise timing features, this Citizen Eco-Drive stainless steel men's chronograph watch also includes a perpetual calendar that automatically adjusts for odd and even months and leap years through 2100. Timing features include a 1/20-second chronograph that can measure up to 60 minutes, 12/24-hour time, dual time (enabling you to track a second time zone), and an alarm. It offers water resistance to 200 meters (660 feet), suitable for scuba diving. And thanks to the solar-powered Eco-Drive, it will never need a battery change.

The silver stainless steel watch case is topped by a hardened, black-plated bezel with scalloped accents that frames the black dial, which includes squarish silver markers, large luminous hands (with red seconds hand), and a date window at 4 o'clock. It's matched with a supple black leather strap with red contrast stitching. Other features include red-accented chronograph pushers and a scratch-resistant mineral crystal.

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 120-day power reserve (270 days with power save function).

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.

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.

Rating : - Inaudible Alarm
Two words says it all. In the past Citizen watches had alarms which were audible. This one is so faint that one would not hear it unless especially listening for it. Save your money. It's too bad. Good quality, but what good is it if it cannot be heard?
