I've had an original 5610 for many years and after owning the new 5610u I feel that this is a HUGE improvement in every way. Casio cemented this watch into the everyday watch category with little to no sacrifices.
1) The LED light looks great. It's easy to read the digits when it comes on. I love the 3 secs option and still retains a warmth in total darkness in the middle of the night. The EL is nice in a vintage way... This new LED is better.
2) My 5610u picks up the signal to sync more reliably than my original 5610
3) The matte black color of the case on the updated version looks more contemporary and plays with the light well with cool effects.
4) Time shown with the stop watch and timer!!
5) The buttons are so much easier to push on my 5610u compared to my original 5610. They definitely changed how far the buttons stick out and that may be my favorite improvement!
6) Long pressing the mode button to get to the home time screen is another huge improvement.
