Product Description

Perfect for professional divers and avid swimmers alike, the Citizen Men's Eco-Drive Strap Diver Watch is both attractive and highly functional. This super water resistant watch withstands water depths up to 984 feet (300 M), so you can keep track of time on your deep-sea expeditions. Clear visual elements of the watch face include oversized, crisp white dot hour markers, large hour-and-minute hands, and an easy-to-read date window perched at the three o'clock. Continuing on the easily visible theme, the large bezel has a deep black background and a crisp white foreground of Arabic second indexes at 20, 30, 40, and 50 seconds, as well as stick second markers along the first quarter. This solar-powered Eco-Drive watch never needs a battery and remains charged for months at a time, even in the dark. The background of the watch face is a handsome black-and-gray waving pattern that complements the striated shape of the strong black rubber band. Other rugged features include a stainless steel case and bezel, fine mineral dial-window protection, and reliable Japanese-quartz movement. A handy buckle securely fastens the band of this must-have diver's timepiece.

Since its foundation in 1930, CITIZEN has promoted a multi-cultural mindset that fosters excellence and creativity. The very name of the brand conveys a deep respect toward craftsmanship and considered as familiar by citizens the world-over. So as a “citizen” of the world, we bear the responsibility to help cultivate a culture of positive change and on-going evolution through our craft. We take that mission seriously and steadfastly welcome what the future may bring.

As a true manufacture d’horlogerie, CITIZEN integrates a comprehensive manufacturing process from creating individual components to a watch’s final assembly. It’s an artisan’s approach to watch making based on pushing forward the boundaries of technology and leveraging our experience toward exploring new possibilities.

One pivotal technological breakthrough was the development of a light-driven watch. CITIZEN pioneered this engineering innovation well ahead of other watch manufacturers as early as 1976, which led to the launch of the highly acclaimed Eco-Drive in 1995. Utilizing electrical power converted from virtually any light source, this extraordinary innovation changed forever the way watches could be powered. Eco-Drive eliminated the need to ever replace batteries, which made it especially beneficial to areas where such specialist batteries were not obtainable. This leveled the field for citizens of virtually every country to be able to experience unrestricted joy of wearing and using a CITIZEN watch.

The product development policy, “The Fusion of Technology and Beauty,” remains a constant motivation for us to merge cutting-edge technology with perfection of design beauty, which as a consequence inspires people to strive to be their best at any time.

CITIZEN launches a new campaign in collaboration with Wieden+Kennedy, Better Starts Now. This is the simple belief that no matter who you are or what you do, it is always possible to make something better — and now is the time to start doing it. We believe that better and now are both infinite, and that there is always a next ‘better’ and a new ‘now’ in which you can start pursuing it. It was clear from the onset of this project that we are dedicated to this ideal…not to the past but to the present, and all the way we can improve it. To help communicate this belief to the world we have created a new global CITIZEN brand movie, brand identity and brand website that represents out Better Starts Now philosophy.

    I purchased this watch just a few days ago, so I won't be able to speak about it's longevity or timekeeping, but I will tell you a bit about the watch which in turn may aid your buying decision. (I am holding back the 5th star until I have some months of use with the watch).

    First, this is a very solid, somewhat heavy pro diver's watch (but not as heavy as Seiko's classic dive watches, such as the "Orange Monster" #SKX781). This watch was made with scuba and skin divers in mind. But surfers, swimmers, water skiiers and other sports and outdoor enthusiasts would like it too. While it is rated for 300 meter depths, it is not meant for helium dives. Of course, like me, you may not be a diver but still want a sturdy, good looking, solid watch that you can use in wet or dirty conditions, requires a minimum of maintenance, and will take some punishment along the way. While it is too early to say definitively, so far I am impressed with the weight, feel and solid construction.

    It is a handsome watch, with alternating grey and black "waves" on the dial, which when viewed in the light, is really gorgeous. The hands and dial are easy to read, and they glow quite well in the dark, especially if exposed directly to a light source just before the lights go out. The date feature is nice, though the window and type size seems a tad small to me. The sides of the one way rotating bezel are highly polished steel, and very good looking. By the way, it's absolutely silent.

    The wide rubber strap is comfortable and attractive -- but take note: the band that comes with this watch is extra long -- made to go over a wet suit, or other article of clothing, like a long sleeve cotton pullover shirt, for example (The band is nearly 11 inches, end to end.

    I have this watch for less then a year.
    At first I loved it and it has a great potential.
    It's looks good a very rough yet elegant.

    Initially I gave it 5 starts on Amazon.
    So you ask why did I change it to 1 star?
    3 month after I got the watch (last March) the rubber strap (where the connecting pins pass through) has broke down.
    Initially I though that the rubber was dried out (although the rubber looks as a very high quality rubber).
    I removed the strap and found out that the connection point to the watch (where the pins pass) is not really rubber but it is hard plastic covered with rubber.
    The plastic is very thin where the pins pass through and now I know that they tend broke very easily.

    I contacted customer service and took the watch to an authorized dealer.
    I have been told that the strap is not under guarantee so I had to buy a new one.
    Well, I liked the watch so I didn't want to throw it away for a strap so I got a new one hoping it will last.
    Less then 6 months passed and the new strap broke in exactly the same place as the old one.

    It is clear now that the straps of this model is defective and hence I wouldn't recommend this watch to anyone.
    A wear of the strap in a common thing (had it also with Seiko) but 3-5 month of lifetime for a strap (~30$) is not very reasonable for a 220$ watch.
    Moreover, this is not a standard strap which one can easily find a replacement for.
    I tried to ask customer service if they are aware of this issue and got a laconic reply that the strap is not covered under the warranty and I need to get a new one.
    It reminded me the answers that customers received from Apple when their 1st gen iPods battery died.
    "We don't offer a technical service so you need to get a new iPod" :)
    Maybe this is the logic behind this watch????

    Bottom line, stay away from this watch unless you would like to visit the service center frequently.

    Update!!! go to and order a $30 band..I'm wearing this again and it looks great on a leather band! old school leather on facebook as well..

    The whole Idea of buying a Citizen ECO drive is to stop having to spend money on batteries...and certainly not to have to replace the band every 9 months...My band lasted 9 months...broke in the same spot as the other reviewers...if I were diving at the time...gone...the band is custom size and fit, (you cant replace it with a standard band) at $30-$50 bucks, that's not acceptable...this watch has dropped in selling price fifty bucks in less than a year...citizen doesn't buy it, if you want to keep replacing expensive bands...I'm looking into a custom made leather replacement...this watch is now a $220 dollar paperweight...I replaced it with the ECO-Zilla...great quality BAND and Watch...I have a $50 Casio Diver that is 3 yrs old and the band is like new...Citizen should at least offer a better quality replacement band that a customer could purchase...No, they keep replacing the crappy band with the same crappy band...makes no sense to me...why make a watch of this quality with a 99 cent band?...

    Great watch but the band is poorly made and will break. Mine broke in less than a year. This is ~$40 fix - not a big deal unless you have to do it over and over. At which point, you might want to consider alternatives. Citizen customer service simply shrugs their shoulders despite fairly strong evidence that there is a defect.
