Manufacturer's Description

Explore new, exciting depths with this men's Eco-Drive 200 Metre dive timepiece. Equipped with large stainless case, black canvas strap, and boldly luminous hands and oversized numbers, you'll be able to easily read the time whether you're diving deep into the sea or relaxing next to the pool. Additional features include a three-hand function, date indicator window, non-reflective crystal, screw-back case and screw-down crown.

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.

My main motive for buying a watch of this type was the eco-drive technology. My last watch had suffered from too many battery changes over the years, and its watertight integrity had been compromised! The thought of never having to open the case and replace a battery is an attractive one.

I like the rugged appearance of this watch, but be aware if you are relying solely on a picture to make a judgement, this watch is bigger than you might expect. It is not 'oversize' though; it measures approx 32mm across the mineral glass, while the casing is approx 42mm across, and lug tip to lug tip is about 49mm. Compare this to an existing watch and you'll see what I mean. However, the size makes it very easy to read, both in daylight and at night. I also like the screw down crown which locks in place to help with keeping the water out.

Overall, I think this is a well made watch offering good value for money. I'm very pleased with it. The only reason I have dropped the score from 5 to 4 star is the puny calendar display; it is disproportionately small to the whole watch and indeed is quite difficult to read. Other than that, it's great!

6 YEAR UPDATE I've had this watch 6 years now, and I thought it might be useful to let you know that it is still going strong. It has never missed a beat in its entire life so far, but I keep the rating at 4 stars simply because of the poor calendar display. Other than that, I continue to recommend this watch highly!

This was a watch that looked good for the size of the dial as my eyesight is now getting worse (close up) so I went ahead and bought it.
I have not looked back the time keeping is first class, and the dial can be read without my reading glasses, I can even read it in the dark as the luminosity is unbelievable.
If you want a watch that never needs a battery, shines in the dark, is easy to read, and keeps time, and waterproof to 200m just for good measure...look no further.

Bought this as a holiday/beach/sea watch to wear instead of my usual one. Citizen make a number of similar looking watches, but most are far more expensive due to the inclusion of chronograph features. Unless you think those extra features are essential, I think this is an excellent piece of kit which feels pretty much bullet proof. Very unusual to find a truly waterproof watch (ie screw-down bezel) at this price - recommended without reservation.

Verified Purchase
I've lived with this watch for a few months now and I have to say I think it's turned out to be a great buy. I love its chunky, (but not heavy), porportions, the clarity of the dial (great for the spec-wearers among us!), both during the day and night (it has a great, long-lasting lume) as part of a stylish package that is also high on practicality with, in theory, no need for any replacement batteries. It's not perfect though. The date display is laughably small, (glasses off, squint to view!), but isn't a major issue for me and the supplied strap is not to my liking at all. I know a lot of people have opted for all kinds of NATO straps to go with this Citizen but I quickly replaced mine with a more comfortable black leather strap (c£10) with contrast white stitching with the whole ensemble making for an understated class act. Bear in mind that the strap sizing is a slightly weird and unusual 21mm although a good quality leather 22mm strap can be comfortably accommodated. These negative issues effectively knock off a star.

If you don't want to spend a fortune on a watch but need it to be highly practical with a contemporary cool form factor, this Citizen is well worth your consideration.

Good quality. Comfortable to wear. Tough. Accurate. Good price. Excellent watch. I bought it to wear while my swiss diver's watch was away having a very expensive service. I've decided to keep on wearing this and to put the other watch on e-bay and spend the money on something more worthwhile....

I bought this because of the Eco Drive.
Basically it's a quartz watch (so keeps accurate time, unlike automatics) but it's solar powered. No more battery changes!
Leave it in the window during a sunny day and you have enough power for 6 months.
However, it can also be charged from any sort light source. So general day-to-day wearing should keep it charged up anyway.

The dial is nice and simple. Not having numbers at 6, 9, and 12 is strange but it's hardly noticable.
It is very quick to read the time.
Date window is a bit small.

The second hand actually lines up to the markers all the way around the dial.

The watch has a screw on back, is water resistant to 200m, and has a screw down crown... If it had a bezel it would be a divers watch!
It's pretty solid and robust and should easily survive day-to-day usage.

The blue/green lume from the hands and numbers is very bright after exposure to just a few seconds of light. It does fade after an hour, but even after a lot of hours in the dark it still has enough lume to easily read the time... very impressive.

Only thing I didn't like was the strap. You can't put extra holes in it and I wanted a position between two places.
The big advantage is that it has normal lugs and springbars. The lugs are 21mm.
It's very easy to take the strap off and replace it with any standard after-market strap.
In fact any normal 22mm leather or fabric strap fits perfectly.
I've tried it with thick leather straps and Nato's (all 22mm) and all look so much better than the strap it came with.

For less than £100 this is one nice watch.
