Amazon.com Product Description
Sporting a hardened, special ops look, the Citizen Black Eagle Skyhawk stainless steel men's flight watch offers advanced timing functions and the latest technology. It's powered by Citizen's unique Eco-Drive, which absorbs sunlight and any artificial light through the crystal and dial to recharge the watch continuously. The fast-forward timekeeping features include time and calendar in twenty-two time zones, thirty cities, three world time alarms, a 99-minute countdown timer, one-touch interchangeable analog/digital time, and 1/100-second chronograph that measures up to 24 hours.

The large round black ion-plated stainless steel case measures 44mm (1.73 inches) wide and 14mm (0.55 inches) deep, and it's topped by a bi-directional rotating slide rule. The black dial background features large white hands with luminous tips as well as luminous square dial markers. It's completed by a black-plated stainless steel bracelet band. Other features include water resistance to 100 meters (330 feet) and a scratch-resistant, non-reflective mineral crystal.

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.

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.

Customer Reviews

Best in class!
I just picked this watch up after realizing I didn't want to wear my Tag watch everyday... go figure. I got this watch because it fits in with my job, military pilot... after comparing all the other similar watches on the market I chose this one. It's comfortable, stong, and it looks great. The coolest feature is the ECO Drive... it's got a battery meter on the dial to show how much charge you have. It's pretty cool when you take the watch out of the case if you put it away for a while it goes into some sort of power saving mode when it's in pitch black and when the light hits it again the dials spin around to catch up to the current time... kinda cool and it lets you know this is really a high tech time piece! The other features on it take a little while to get used to. I love the time zone features and that this has the look of an analog watch with all the features of a digital watch. Haven't had a chance to use the bezel yet... more of a novelty than anything else I think... however it gives the watch a unique look and distinguishes it from a lot of other watches... if you're comparing it to other watches like it, with the bezels and all. I would definately go for this one. I picked black because it's a little different than my other watches and because I prefered a black watch in what I wear to work. Just pick what color you like best, there's a few different looks to choose from. The black is really good looking though. It's got the competition beat in features, value, appearance, comfort... you name it, this watch is best in class! You won't be disappointed!

Sleek Design
I replaced my old (10 years) Citizen Skyhawk watch with this one. I had to replace the battery every 3 years or so. The last time, the watch shop screwed it up. So, I was familiar with the way this watch works. It does not have a light (niether did th old one) so it's tough to see the digital portion at night or in a darkend area. If you are a pilot, or in the aviation industry and use UTC time, this watch comes in very handy as there is a dial on the face that tracks UTC time. It's slightly heavier than the older versions, but I figure that's due to the Eco-Drive. Overall, I am very pleased with it.

Great aviator for the price
I got this watch two months ago and it was exactly what I was looking for. It has all of the bells and whistles and easy to maneuver. It's my first Citizen eco-drive and probably won't be my last. I have two Oakley's, GMT and Detonator, and a Rolex Submariner. I saw this watch around Christmas and no retail store in the area carried them. Still don't! Price was great since I don't do retail.
