I love Citizen watches, currently owning three. I've worn a Promaster with eco- drive for the last year, and it's a pleasure.  Fortunately, it does not require use of an owner's manual to make adjustments.  And then I have a Navahawk and the watch under consideration, the Eco- drive perpetual calender chronograph.  This watch is like the Navahawk only in the abysmal quality of the manual and the difficulty in making any adjustments to date and time. Believe it or not, the Navahawk is actually harder to set than the perpetual calendar chronograph. Fortunately, the calendar chronograph came with a mini CD which enabled me to get the watch set up without searching the net for advice. My experience with my other Citizen eco- drive is that once you get it set, it keeps  time accurately, no batteries to change, so you won't have to bother setting it again for a long time. Those of you with large wrists should be aware that the strap is both too stiff and too small. The case of this watch is around 47 mm, so it's made for big people. Why Citizen put a smaller strap on it is beyond me. I have to use the next to the last hole in the strap. You will find that a larger replacement 23 mm strap may cost over seventy dollars and will not have the rose gold buckle of the original.  You may be able to detach the buckle on the original strap and put it on the new one to make it match. Others have commented that the face of the watch is supposed to be brown but is/ was black.  The watch I received has a dark brown face. This is a quality Citizen product flawed by the manual, and dare I say complex setting routine and by, in my case, a strap that should be on a smaller watch.
