Manufacturer's Description

Sleek and stylish, the silver-tone Citizen Eco-Drive 180 Titanium men's watch will keep you going at home and at play, thanks to its solar-powered Eco-Drive technology which never needs a battery change. The large, round watch case (measuring 1.5 inches wide) and bracelet band are both made from solid titanium, which is nearly 50 percent lighter than steel, but 30 percent stronger. It's also particularly resistant to salt water corrosion, as well as hypo-allergenic--perfect for those with metal allergies.

It features a stylish, polished silver bezel with screw-down accents, which integrates seamlessly into the tapered bracelet band that balances brushed and polished finishes. The band is joined by a push-button foldover clasp. It has a blue dial that's supplemented by silver luminous hands (with seconds hand) and dial markers as well as a date function at 3 o'clock. Other features include a scratch resistant mineral crystal with anti-reflective coating and water resistance to 100 metres (330 feet)--suitable for swimming or snorkeling, but not diving.

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 180-day power reserve, and it can be recharged with just 1.5 hours of exposure to light.


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.

I got the watch from my girlfriend for christmas last year and it has been the best watch I have ever had. It's not too heavy but feels well made, the face is easy to read and minimalist which suits people who don't want a fancy watch. I would reccomend this watch for anyone who likes simple watches. Plus, the eco-drive means you never need to replace the battery unless you have it for many years. I have had no problems at all with it. It's been in the ocean and didn't react with the salt which has ruined a few watches I've had. Nothing seems to leave a permanent mark on the strap. The glass hasn't scratched and I'm not particulary careful with it. Overall, a great watch!

I love this watch. The date display is way too small for me to read though!

One niggle is that I had not realised I would have to pay extra to get the watch strap adjusted. I assumed it would be reasonably easy to DIY - but not - no instructions provided and having looked up the method its clear you need a special tool to do it.

I got this watch as a Christmas present and I really like it, to the point I wear only in special occasion as I tend to abuse the stuff I wear due to the nature of my work. Soon after purchase, one of the little screws on the bezel came off. I sent it back to the manufacturer and they promptly returned it repaired plus they polished the glass that I had badly scratched it at work (yes I wore it once and I almost wasted it!).
Overall quite happy with it although I can't wear it as often as I would like
