Amazon.com Product Description

One of the most advanced chronograph watches made by Citizen, the Eco-Drive Calibre 2100 men's stainless steel watch also offers stylish lines that nicely complement both business and casual couture. The chronograph timing function includes 60-minute, 12-hour, and independent second-hand subdials, as well as a center sweep 1/5-second hand. It also has a reset button that instantly returns all the chronograph registers to zero.

This large, round watch has a thin, flattened bezel with an exterior tachymeter reading in gray. The patterned silver dial face is accented by black subdials, and it offers gray 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 Story

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 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.

5.0 out of 5 stars My favorite watch!, April 17, 2006

This review is from: Citizen Men's AV0031-59A Eco-Drive Calibre 2100 Watch (Watch)

I am a collector of watches, to my wife's dismay... But, this is a beautiful watch that I am very proud to own. This is my third Citizen watch (among many others), but my favorite of the bunch. It is a bit on the thick & heavy side, but that is what I was looking for; something with substance. The luminescent hands are very bright and long lasting. The watch takes a good amount of sunlight to fully charge, but even in a partially charged state, it works just fine. Once fully charged, it rarely, if ever moves off of the fully charged indicator.
I have the stainless steel band and it has proved to be durable and attractive. The titanium is tougher but has a satin finish rather than a glossy finish.
I tend to be hard on my crystals and so far, so good. This one has a flat, hardened crystal and looks great.
Get this one, you will love it! Amazon has a great price on it and Citizen stands behind their products.

UPDATE: 10/17/2011
I am still wearing this watch! The only indications of wear on this is the bottom of the band and the clasp; there are scratches, but I see this as normal given how much I wear it. The titanium watch might fare better in this area. The crystal is still smooth and clean and all functions of the watch are good. So, just to post a long-term follow-up saying that I still love this watch and it is working as well now as on day one!

5.0 out of 5 stars Calibre 2100 is great, February 22, 2007

This watch is gorgeous! I sized it as soon as it arrived and put it on before hitting the door to catch a plane. The bracelet is beautiful too. Just be careful when adjusting the links . . . there's a sleeve for the link pins that has to be put back in to get the pins to stay in. All of the dials are easy to read. I like the size and weight of the watch too. The Eco Drive is a great feature, no winding and no special case needed as with the automatics . . . just expose the watch to light and it keeps going. The meter to show how much reserve power is in the batter is good for letting you know when it's time to give the watch some sun.

5.0 out of 5 stars A Wonderful Watch, October 1, 2009

This review is from: Citizen Men's AV0031-59A Eco-Drive Calibre 2100 Watch (Watch)

I am writing this review as a long term user of this watch. Those who have reviewed it after only a few months of ownership cannot have a long term perspective. I am going to try to fill that gap for those who wonder if the watch will last in the long run.

I bought my ECO Drive Caliber 2100 at a local jewelry store about 5 years ago. I love watches but I'm not a collector. But, I do have small drawer full of working watches. I have worn chronograph type movements, including analog quartz, digital, and automatic mechanical, exclusively for over 30 years. I buy a new watch about every 5 years whether I need one or not. I did not need this one but I could not resist. It is flat beautiful, better in person than in the photographs. The detailing of the dial is up to the best around. It has very subtle details that keep me looking at it often. I still think it is amazing.

I tend to be hard on watches. I do a lot of hobby type work and often I forget to take the watch off-a bad habit. This has lead to scratches on the crystal but the case is unmarked. I agree with others that a sapphire crystal would improve the watch. The stainless steel band is high quality and has proven strong. It does have a few scratches, though. Since I wear the watch every day, I guess it is natural that the back will collect scratches and mine has.

Functionally, this watch has been perfect. I have had zero problems. It has never been serviced but service is due. Time keeping is great. I only set it when the time changes. The chronograph works great but it does not do lap times. Not a great loss for me. The alarm does not get used much because the sound is so weak. The dial illumination lasts through the night. My old eyes sometimes have a hard time seeing the fine markings on the chrono dials depending on the light. Usually, this is not a problem but I wish the markings were a little bolder. The Date Window is set rather deeply into the dial face and is small. Often, I have to adjust the light angle to see the date. This is not usually a problem but it is something I would change. Setting the end of month date is easy because the first detent on the crown moves the date indicator only. There is no need to reset the time. This is a very nice feature. Other than the occasional splash of water when doing things around the house, I have not challenged the water resistant specification. So far, water has not been a problem.

Battery charge works very well. During daily normal use (I have an indoor job), the charge indicator never moves off full charge. A few months ago I bought a new Casio digital and put the Citizen aside for about 4 months in very reduced lighting. The charge indication went down to about 1/2 charge. The watch continued to keep perfect time. Eight hours in bright light brought the indicator up to full charge where it has remained as I again wore it daily. This is very impressive performance, indeed.

Others have commented on the weight and size. It is heavy. It is large. My wrists are large and this is not a problem. The fit is fine. Smaller wrists may not work as well with this watch. As for the weight, it does seem heavy if you pick it up. But, when I am wearing it I don't notice the weight. I have tried the titanium model and I like it. I may buy one.

All in all, this is the best watch I have owned. It is accurate, convenient, versatile and rugged. Did I say it is beautiful? It looks much more expensive than the selling price. I don't think you can go wrong with this one.
