I've had my watch for a few days now and really like it. One feature is that the hands and numbers glow a cool blue in the dark, rather than the more common green seen in other watches.  I have a more expensive Tag Heuer, but the quality bracelet on this Citizen compares very well.  Regarding size this watch looks good on my 7 5/8" wrist.  I have friends with huge 52mm watches, but I find those too massive and cartoonish.  This watch is definitely big, but I could wear it to the office with a tie, or to the beach with shorts and a t-shirt.  Tech specs show it measures at 42mm, and I came up with 42mm with a caliper, but if you measure strait across horizontally from the 9 to 3 position, including the screw down crown, I get 46mm across.  The stainless bracelet tapers down to 18mm wide, with a nice clasp.  The slide rule function is very smooth with zero play. One important reason I bought this watch is the Zulu time feature, which is easy to set, and I like the fact that it runs on light, therefore I will never have to walk into a store and pay to have the battery changed.  Note that the crystal sits higher than the surrounding metal bezel, therefore possibly exposing it to scratches.  This was sold and shipped by Amazon.com LLC when I bought it.  The only change I would make?  I would be willing to pay more for a sapphire crystal, but am happy with this watch and price.
