I'm in the process of purchasing another Rolex. I love the GMT 116710 but my only complaint is the center polished part of the band tends to get scratched easily. I love the Sub but it seems that's the most worn workhorse out there. Now I'm a larger guy and is the Sub a larger watch face vs. the GMT? Sorry to be lazy here as I could look these up but I wanted your thoughts on the versatility as well as which one would hold value IYO. Thanks much, Mark
