It's easy! Just flip your Saturn over and look for the center-most label. Both Model 1 and 2 units quite clearly state the month and year that unit was manufactured in.

That pic is of my Model 1 Saturn, it was manufactured in August, 1995 as seen.
My Model 2 Saturn was produced in July, 1996 but I don't have a pic of that.
How about the rest of you?
