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.

My favorite 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…
A Wonderful 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…
