Eh, it's kind of a collector thing but it's also the history of the watch. Plus it can prevent you from buying a knockoff or a newer ExplorGMTmariner that is built into a much rarer watch. Depends on the day but when I was really into flipping it sometimes added a lot of money to the price and depending on what I wanted to do, I sometimes wouldn't touch a watch without all that shit. Now, if I came across the right year and model GMT or Explorer, I wouldn't give a rats ass. I'm buying for me in this case.
