And once again, we encounter the frequently asked question about which UC Timeline Gundam (a.k.a. older Gundam) titles is the one to watch first. Actually this is rather a moot question. Unlike the stand-alone Alternate Timeline Gundam series' (with the exception of Turn A Gundam), the Gundam series' set in the UC Timeline are directly related to one another. So which should you watch first? Definitely the very first of them all: Mobile Suit Gundam (the trilogy movie version at least, the entire TV series version at most).
