Casio DBC150B-1DF - Ryan Gosling - Half Nelson

Ryan Gosling, as Dan Dunne, a young urban high school teacher in the movie Half Nelson, wears a Casio DBC150B-1DF data bank calculator watch.

The multifunctional Casio watch features a 150 page databank (8 letters and 12 numerals per page), EEPROM memory protection, an 8-digit calculator, EL backlight with Afterglow (see image on the left for the blue effect), world time, daily alarm, countdown timer, 1/100 second stopwatch, hourly time signal and a calendar (pre-programmed until the year 2094).

The watch from the movie has a white, luminous keypad and black case (DBC-150B-1DF), but is also available in other colors, for example the metal band version (DBC1500B-1) or the more simple (no luminous keypad) plastic version (DBC150-1). If you need more memory, there's another similar model with 300 page databank (the DBC310-1).

The watch is currently hard to find, but you can try on eBay.
