No, I don't "need" a GMT function, but does anybody really need a chronograph/GMT/power reserve.....it just looks cool . But the 111 is very good looking as well. Love the sandwich dial. Right now I have a gen Tag Aquaracer chrono that I have had for about 4 years. I wear it pretty much every day and I love it, but time to add to the collection. After seeing how great these reps are, I doubt I would ever pay for a gen again unless I come across some stupid money. But anyway, I kind of had a feeling that the 111 would be a better "bang for the buck". I will just have to get both eventually.
