This is a combination watch / vortex manipulator, worn by the character jack harkness: http://tardis.wikia.com/wiki/Jack_Harkness.
Its main use was to teleport the wearer through time and space (although this one just lights up). This uses a very similar battery and led to my sonic 'ible: http://www.instructables.com/id/how-to-make-a-simple-sonic-screwdriver/. the band is leather, with a button holding the flap down. On the inside the watch face is just a boring old digital watch. then you'll want to cut some thin wood for the top to fit around the watch and led.

not bad but it would be nicer if you used thicker leather , still i like it , oh and it would be nice if you added some velcro so it can hold on better

I originally was going to use a magnet, but it wasn't strong enough. Yes, thicker leather would of been better, but o well.
