So I’m in a tough situation and need some advice. I currently own the series 3 stainless steel Apple Watch SB but just found a hell of a deal of a brand new series 4 aluminum 44mm cellular that I got for only $400. Should I sell my series 3 SS for $400 to someone that is interested and keep the new series 3 or sell the series 4 because I’m worried about the durability of the screen of the aluminum model..? I do want the new series 4 stainless model but man it is expensive. What would you do? Post your opinion.
