Which one do you like best?

Both watch styles are very different, but I prefer the David Yurman by far. It's more artsy and feminine looking and just more pleasing to the eye. The David Yurman watch is the classier choice, I think!
Good luck with your decision!
 
Cartier that DY one looks like it came from one of those vending machine things, where u twist it and out pops the bubble with a present. Where i am from DY doesnt even have a store so i dont know if thats the reason, but it looks cheap and tacky to me IMHO. although I think it has more potential IRL than that pic. but of the too Cartier is def. my choice
