Casio Illuminator MTD-1049
The light is on in this picture
Please note that I pressed the lume button (the light stays on ca. 5 seconds) for this wrist shot. Not only to show the two extremely bright white LEDs, but also because it is almost impossible to take a good picture of this watch with a very thick (my guess is over 4 mm at the center) mineral crystal with no anti-reflective coating. The wrist shot here does not do the watch justice, it looks a lot more impressive on the wrist and people will probably often confuse it with that famous brand from Geneva.
