Rated 5 out of 5 by from Perfect I purchased this on my last cruise & find it to be perfection. It has everything I could want in a watch - timekeeping, perpetual calendar, no need to replace battery, swimming down to 10 bars. I own many watches & this is by far my favorite!

Rated 5 out of 5 by from Very Nice Watch! Wow! First off, I got a great bargain on the Citizen Watch website. I am a stickler about having the correct time and this watch is about perfect for being an "Atomic" watch as there is. Wonderful styling with the rose gold. Formal enough to wear with a suit, yest casual enough to go with jeans and a sport coat. ! minor detail that was NOT Citizen's fault. I had ordered too large of a size, but watching a You Tube video, I was able to quickly remove 2 links for perfect fit. Very very happy with my purchase.

Rated 5 out of 5 by from Citizen World Perpetual A-T Good looking watch, fairly simple to program initially. Am wondering how the daylight savings time function will work. With that said, this review might be a bit premature.

Rated 4 out of 5 by from Beautiful watch; hard to set. The watch is gorgeous! When it arrived it was completely powerless, so I had to wait til the next morning to set it. Setting the watch was WAY more complicated than I expected. You should have it least 15-30 mins free when you start. And I have yet to actually recieve a time signal, although I haven't worn it much yet. Once I got it set, it works perfectly! Very happy with my purchase.

Rated 4 out of 5 by from Receiving a watch wit no power. It needs power to start. My watch came-powerless-I attempted to adjust and set, nothing works w/o power. I called citizen and e-mailed several times, I was given case numbers, never got a response. I took to a jeweler, he said it needs power. Put it in light/sunlight, it started working. When I got a little juice, I adjusted and set, all good now! Just remember, it has to have some power.
