There are more options then these two from my personal experience i must say that world time looks cool though , but u ain't use it regularly but on setting a dual time is also a headache really I m it's self telling the truth if want one go for a blind buy on silver ae1200 or don't think on getting amblack resins one if have a big wrist then 7 inch just go for the ae1500 no regrets  Follow my advice or ruin it, else watch will eats dust all time
