Prime Time WatchMath Geeks are in awe about this fantastic 33mm leather banded watch. Rather than have the same boring numbers as any other watch, the Prime Time Watch only uses prime numbers to express the time. Naturally, 2, 3, 5, 7, and 11 remain untouched because they are already prime. But for the numbers 4, 6, 8, 9, 10, and 12, the watch really gets imaginative. A great gift for the math lover in your life! (#4423) Item in stock unless noted above.
