Amazon.com Product Description
More than just a pretty face, the Citizen Eco-Drive Calibre 2100 men's stainless steel watch offers stylish lines that nicely complement both business and casual couture. But it's also one of the most advanced chronograph watches made by Citizen, offering a reset button that instantly returns all the chronograph registers to zero. The chronograph timing function includes 60-minute, 12-hour, and independent second-hand subdials, as well as a center sweep 1/5-second hand.

This large, round watch has a thin, flattened bezel with an exterior tachymeter reading in black. The black dial face is accented by black subdials, and it offers white luminous Dauphine hands (with seconds hand) and a date function at 4 o'clock. The stainless steel bracelet band is joined by a fold-over deployment clasp. Other features include a screw-back case, screw-down crown, scratch resistant mineral crystal with anti-reflective coating, and water resistance to 200 meters (660 feet).

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 240-day power reserve, and it can be recharged with just 3.5 hours of exposure to light.

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

Love My Ctizen Calibre 2100
I picked up my Citizen Calibre 2100 about two months ago and I absolutely love it. I opted for the one with the black face since I found it a bit easier to read.

The watch itself is quite substantial. It has a real solid feel and appears to be very well built. I have taken the watch into pools and the ocean on several occasions (though never to any significant depth) and have yet to see any kind of water intrusion. Just make sure the bezel is fully locked down!

The watch itself looks magnificent. My father has a Breitling Navitimer and I think this watch looks every bit as good as his. Yes, I know it's not a Breitling and it's like comparing a Volkswagen to a Bentley, but I've always liked the look of the Breitling and I think Citizen does a good job capturing that look with the Calibre 2100.

The "Eco-Drive" on this watch's designation means that it is solar powered. I find this to be a very nifty feature. I have yet to see the power meter dip below full charge, though it is summer and I am wearing short sleeves a lot.

I highly recommend this watch.

A quality product and very versatile
This watch is perfect for just about any use. Rugged, classy, practical, very, very stylish for everyday use but yet still perfect for dress occasions. I've owned Citizen Eco Drive watches before and they are truly quality products: durable, reliable, and reasonably priced.

This watch defintely has the "WOW" factor and I would not hesitate to HIGHLY recommend it to anyone. A Lexus quality product for a Toyota price.

A real Man's Watch!
I got this watch for my husband for our 9th anniversary. I think he has told me "I love my watch!" at least 2-3 times a week since he got it not quite a month ago. It has a good weight, keeps excellent time and has several other useful functions. It has glow in the dark hands that one can actually read in the dark! I highly recommend this watch. My husband had been looking at this watch for some time and did a lot of research before choosing this particular timepiece.
