Initially I was hesitant about this watch because I noticed that some people said that watch was heavy and too big, however, I am very pleased with how it fits.
Before buying it I went to Macy’s and tried on the titanium version, which felt alright.
After buying it I took it to Fred Meyer to get 3 links taken off. The watch tech said that the band is prone to breaking later down the road due to some special pins that it has. Although the watch was not charged very much when I arrived, putting it on the window sill during one sunny weekend charged it fully.
After a couple months of wearing the watch to work 5 days a week I have grown to love this watch. The weight and size is perfect for my average wrist. I highly recommend getting this watch.

I’m a big guy who needs a big and masculine watch. Watches less than 40mm just don’t look right on my wrist. I was in need of a classy, sporty everyday watch that I could easily wear to work or to a night out on the town. I ran across this Citizen watch and after careful consideration I purchased it. Two weeks later I have absolutely no regrets. What attracted me to it was the sheer size and masculinity of it, plus the busy black face with chronograph and energy measure…all set off by a classy stainless steel band. It definitely is a heavy watch, and that took some getting used to. But it’s so damn interesting to look at and it’s gotten universal praise from my girlfriend, friends and co-workers. I love that it’s solar and will never need a battery replacement.
As far as cons, there are few: I wish it had a sapphire crystal (better scratch protection) because the crystal is so prominent, and if Citizen offered the black face (and not the two-tone grey face) in titanium rather than steel, it wouldn’t be quite as heavy. But I am thrilled with this big watch and look forward to wearing it frequently for years to come.

I just got this for Christmas from Fiance and I gotta say I love it!
It’s larger than I expected. It’s also heavier than I expected. In other words, it’s a girthy machine.
I also wasn’t aware of the asymetry of the case. The right side is circular, but the left side is artistically slanted, flairing outwards to the inside of the wrist. I must say, from a industrial designer aspect, this unexpected aesthetic absolutely makes the watch. It’s subtle surfacing like this that makes you look at it just a little bit longer.
As for the functionality, I was a little worried when I saw how thick the manual was. But, the original packaging also came with a mini CD ROM that has a wonderful tutorial to get the watch set up. It takes you through the time, then the date, the alarm, the chrono, the tachymeter, and how the eco-drive system functions. I must say, it’s much easier to use than I expected.
I would like to thank a previous reviewer on here for suggesting the black face. This is definitely the model to get. The brushed alluminum, black face, white dials provide class and contrast. It’s very easy to read. I’m glad I didn’t ask for the white face (my first choice).
Overall, this is an exceptional piece for the price. It has that perfect blend of geek and sleek that’s a tricky line to tread.

After owning this Citizen Eco-Drive drive for a short period, I simply have to echo the other reviews on here and say that this is an outstanding watch. It’s large, bold styling looks great on my (large) wrist. It is solid without being overly heavy.
The alarm function is a nice bonus, though it is definitely not loud enough to wake up anyone but the lightest sleepers (in case you had considered that). The stopwatch feature actually does come in handy on occasion. And for those who have only dealt with traditional quartz watches in the past, it is a pleasure to have the Eco-Drive feature and not have to concern yourself with periodic battery replacements.
Again, a great watch, and highly reccomended.
