As a self appointed nerd I have a special fascination for watches with binary displays or with morse code readouts. It seems as if such watches now have become designer objects. One reason may be that since everyone has a mobile phone with a clock these days, design can be promoted at the cost of functionality. Anyway, here are some nice watches to choose from for your wish list!
Personally I find the watches from The One to be among the nicest. Here is the Slim Square. The display is a bit hard to read, binary as it is. The trick is that the left-hand side shows the hours and the right-hand side minutes. Then just add up to get the hours and the minutes.
