Maybe the newer ones, but the 2000 series(actually released between 1999-2000) have actual wire bonded LEDs, albiet they have the magnifiers over the digits, giving a slightly "pop-eyed" look.  I have two that I have been really happy with, despite having few features and using a seperate button for time and date.  Maybe I just like them because they were super cheap
