I have both pam and rollie sport watch. Well, some 5 years ago, I feel very happy with my Pam since there werent many Pam around. But look like Pam is getting common now. Of course, you may wanna say there are still many more rollie out there which is true.
Look wise, I will say Pam has a better and unique look if your wrist is big enough. But if you are thinking to flip your watches in the future, you are still better off with rollie. I know that i can trade in my rollie now without losing money but will lose 20% minimum for my pam.
