You shouldn't have any issues with either watch. My vote goes to the Longines just because I am fond of their watches and they have a great reputation for well-built pieces. The Certina is nice as well, but it doesn't have the class of the Longines imo. Neither watch will likely hold much of their retail value in the long run, so make sure you pick the "one". Having said that, I don't think you can go wrong with either...both very cool, unique watches that don't have the cult like followings of some of the other brands on WUS.
