Here's another one of those cryptic watches that make you guess what time it is, the JLr7 by e35 whose little J and L-shaped LEDs seem to light up at random. Even its name seems arbitrary, but check out the top row of LEDs and you'll see: JLr7. How does it work? The first three rows of lights show the hours in a 12-hour format, the fourth displays quarter hours and the rest of the rows show minutes and seconds.
