I got my Core Light Green from DataVision. The bezel is loose, it does rattle if I shake the watch. I do not know yet if this is a problem across the board with the Green Light only or just my watch or a bad batch from DataVision. So please let me know where you bought yours, if the bezel rattle when you gently shake the watch and also has play. I have only 2 weeks to return it.
Thank you very much
