Well yeah you can start with Zeta, but you'll miss all the historical references, cameos from past characters, the importance of some major characters from the first Gundam who are also central figures in Zeta etc etc etc. Best to watch in chronological order IMO.
Original Gundam - War in the Pocket - 08th MS Team - 0083 Stardust Memory - Zeta Gundam - Double Zeta Gundam - Char's Rebellion - Gundam Unicorn.
You're watching Gundam Unicorn aren't you? Then you've already started on the Universal Century timeline, only you've skipped 20+ years of history .
