Welcome to the forum! Let me start by saying that marriages are overrated. :wink:
You probably know that there is a difference between "true" GMT (12 hour hand to be set independently) and "stay at home" GMT (24 hour hand to be set, usually also involving the hacking second).
If you want to use the watch as a frequent traveller, the "stay at home" kind is a real pain to set. As far as I know, Omega's SMP is the least expensive version of a "true" GMT watch, with Rolex coming in second. All other "true" GMT models exceed Rolex prices. Your post isn't quite clear on whether or not the watch you have is a GMT. If it is, stick with what you got - if not, swap it for a GMT version. Either way, I think of Omega's SMP GMT as a great watch and a bargain for what it offers!
