I have seen a number of binary watches out there, but most of them have some odd way of reading time. This watch is much more straight forward. One row is the hour, the other row is the minutes and you read them just like you would any normal binary number. They even give you the value of each dot so the worst you have to do is a little addition in your head. That may still be a bit too much for some, but they make some nice Mickey Mouse watches for them.
