Every time I go pick up my son from school, I see this oddly dressed guy walking back and forth up the sidewalks along the road. The dude has these huge pants on with about a million zippers on them. Yanko Design has the perfect watch concept for this dude. The watch has four zippers on a leather band and no watch face.
Each of the pull tabs on the zippers shows one number to display the time. The hours are on the top two zippers and the bottom two show minutes.
The time only shows up when a button between the bottom two zippers is pressed. It's very easy to make out the time, even if the watch sounds a bit confusing.
