The radio-controlled time keeping is highly unreliable. I have a Casio with this feature for over 8 years, and normally it picks up the radio signal a few times a year. I adjust the time manually if the clock drifts for over a minute, and I had to do it a few (4 or 5) times so far. Actually, not that bad.
Citizen's new World Chronograph A.T. combines Eco-Drive solar power with radio-controlled timekeeping that automatically adjusts the time and calendar across 26 time zones. The 43mm stainless steel watch features a green dial and is currently only available in the UK.
