World Perpetual A-T is rated 4.4 out of 5 by 19.
Rated 5 out of 5 by from Love the design Just bought it 3 days ago (but I had Citizen watches for over 20 years so I'm not worried about reliability or durability). More people are noticing this than my Longines. BIG deal. What can I say? classy, waterproof, perfect timekeeping, solar powered (no need to change the battery or to wear it permanently as I need with automatics). Plus it's not as complicated as other watches (I'm a minimalist). I really LOVE it.

Rated 1 out of 5 by from Does not keep proper time I purchased this watch 8 years ago and have you readjust it every month. Because of the difficulty of resetting it (it has a 20 page booklet on how to set the time, date ,etc including the leap year). I took if off and I kept it on the window sill where it gets diffused light for over 6 hours in the AM. I left the watch there for over 6 months because I forgot that it was there. Now it does not have the right time nor the right date now I have been unable to change anything. This watch is supposed to have GEO-CLOCK which means that it is reset every 24 hours by the World clock. I would not purchase another one and you should think long and hard before you do too.

Rated 5 out of 5 by from Great-looking and keeps perfect time Love this watch. Very functional with radio-controlled time-keeping. Solar-powered is a key feature. Also very legible face and overall beautiful appearance. Highly recommend.

Rated 4 out of 5 by from It’s perfect for me. I have a couple of quibbles. First, it is exactly what I wanted. That may not be true for everyone. I wanted a watch the freed me from batteries and messing with the date after 30 or 28 day months. The face is easily readable in sunlight or indoor lighting. I have a small wrist and the strap fits well and the case doesn’t look clunky. The watch is good for both dressy and casual occasions, perhaps leaning a bit towards dressy. My two possible problems: The luminosity is feeble, nice after stepping into the dark from bright sunlight, but useless after a few minutes in the dark and the only the hands are luminous at all. This is not an issue for me, but might be a deal-breaker for others. I’m not sure where to get replacement bands since this one looks non-standard and this is the primary reason for a four star review. Perhaps someone can help me with this since I have searched high and low and come up nearly empty. I would like to have a metal band that is a decent match for the watch. I don’t mind swapping the bands in and out as occasions dictate.

Rated 3 out of 5 by from Almost Perfect The watch looks great but the city names are so small its extremely hard to see! If the city names were slightly bigger then I think this would have been the perfect watch for someone who loves to travel.
