World Time A-T is rated 4.7 out of 5 by 13.
Rated 3 out of 5 by from Nice Watch, But... Only bad thing about this watch is the big hand. The big hand is too narrow and many times difficult to see. I have to turn the watch at an angle in order to have light reflect off the big hand so that I can see it.

Rated 5 out of 5 by from Amazed! I bought this watch yesterday. I took the time to watch the instructional video to learn how to set the watch and used its other functions. I was unable to get a daytime radio signal for the watch to automatically do a time correction. To my delight when I get up this morning it had received the radio signal and the time was precise to the second. This is 1 beautiful timepiece.

Rated 4 out of 5 by from Great watch! I purchased this watch at a retailer that was 'out of box', and so it did not come with a manual or anything. It took me a few days of YouTube research to figure out that the hands were not calibrated correctly, but once I got it calibrated it has not missed a beat.

Rated 4 out of 5 by from Citizen watches are my favorite I bought this watch in early February and I really like it except for the small minute hand but the overall beauty compensates.
