    I really like this watch . The blue of the crystal gets people's attention and it keeps excellent time. It looks good while wearing a jacket and tie as well as jeans and a shirt. I also really like the strap. It isn't that cheap plastic strap that cracks and breaks. So far , it is holding up to daily wear.

    My wife got me this watch for Father's Day (at "Father's" specific request ... lol). It's now my third Citizen "Eco-drive" watch, and it may end up being my favorite.The gleaming finish, stainless steel case is a flawless beauty. The size (44mm diameter) is just right for me ... not too big, not too small, and not too thick.The face is a kind of slate-blue, micro-grid pattern when you're looking at it straight on, but it flashes a much deeper, brighter, iridescent blue as you move it around in the light. The iridescent blue color is what you're mainly seeing in the listing photos ... probably why a few reviewers complained about the accuracy of the photos. That color is definitely there, but it isn't as dominant as the photos might suggest.Citizen has equipped this watch with a "sapphire" crystal, which enhances the blue tones of the watch face when you view it at an angle. Perfect choice.It's water resistant to 10 ATM (i.e., 100 meters, 333 feet) making it fine for swimming, showering & snorkeling, and I actually trust Citizen's water resistance ratings on their products, unlike the hordes of other, cheaper competitors out there.The stainless steel hands are imprinted with a strip of light-blue lume that glows VERY brightly when the watch is first brought out of light, then fades a bit, but remains visible in complete darkness. The movement of the second hand is very precisely aligned with the second markers on the outer ring of the face.The watch has three, chrome-ringed subdials: day of week, day of month (same size), and 24-hour dial (a little smaller than the other two). The letter/number characters on the dials are too tiny for most people to easily read, but once you've taken a close look at them and know how the dials are set up, it becomes easier to see/know what the hands are pointing at, whether you can make out the characters or not. For me, the overall look/feel of this watch is WELL worth a little minor inconvenience in the size of the markings on the subdials.The crown is 3-position: 1) closed; 2) turn counterclockwise to advance calendar day subdial; 3) turn clockwise (or reverse for hour/minute hands) to adjust time and advance day-of-week and 24-hour subdials. All very easy to "feel" and do.The band is beautiful, nicely finished leather, and it even comfortably fits my 8-inch wrist, with adjustment holes to spare, but I've already got several watches with essentially the same chocolate brown, croc-pattern band, so I opted to replace the factory band with a brown leather/navy blue "NATO" style band, as shown in the photos. I think the band makes the watch look even better. The EXACT lug width of the watch/factory band is 23mm (I measured both the lug width and band with a caliper, so trust me, not any contrary listing details). 23mm is an odd size that's difficult to find replacements for, but I was able to fit a 24mm replacement band in there with very little trouble (you'll need to transfer the spring bars from the original band), and as you can see, it looks fine.I expect accuracy to be as good as the movements in my other Citizen watches, which are generally rated at (+/-) 20 seconds a month, and Citizen's "Eco-drive" power system is a marvel. Once fully charged (Citizen recommends exposing the watch to direct sunlight for 11 hours before starting to wear it regularly ... much more than that for other kinds of light), the power cell will thereafter stay charged on much shorter exposures to light, and can keep running for up to 6 months in total darkness.In sum, this watch is a well-designed, multi-use workhorse that's beautiful, functional, and can easily go from workout/swimming, etc., to a night on the town or casual business meeting, etc. I love it. Only wish Father's Day came more than once a year ...

    I got this watch for Father's Day after admiring it online for a while. I love it! The face is a dark blue which can be seen with a little light on it. The smaller, inner dials for day of the week, date, and time of day are small but I can see the date (smallest of the 3) with a close look. The watch is a great size, both width and thickness, for my wrist and I have med-to-large sized arms/hands. The band is more reddish than I was expecting but seems like a high quality genuine leather. One thing I wasn't sure of but excited to have: the crystal is SAPPHIRE! The back of the watch says it, though my pic is a bit blurry. I won't have to worry about the crystal getting scratched, sweet! Love the Eco-Drive so I'll never hafta replace the battery, too. Great watch, I'm sure I'll enjoy it for decades!
