The feature like: eco-drive, world clock, radio-controlled make it a perfect companion to anyone who travels a lot. The only negative is viewing time in the dark as the hands(or any part) of the face is not illuminated.
I love the look of it , fits nice with a suit. I do try to wear it during the the day only , The Dials are a bit difficult to read in the dark. That's when the promaster comes in handy.
This is my latest Citizen watch purchase, becoming number 6 in my collection, which is to say that I am committed to this brand. This is a beautiful watch, records time accurately and has many interesting features. However, as other reviewers have noted, it is virtually impossible to read in certain lighting conditions. So to be on the safe side, wear this watch as an attractive piece of jewelry, but strap a $20 Timex to your other reach to tell the time.
I really love this watch, it has every feature I've ever wanted in a writewatch. It's even black / copper which is unusual and awesome. However, the hand and the hour markers do no glow. This makes it impossible to read at night and unless you tilt the watch exactly so, almost unreadable during the day. This watch needs to have glow hands, but does not. A significant usabilty problem.
