Sudoku is a popular numbers-based puzzle game for people with time to kill. Think of it like crosswords for the numbers-leaning set. It's gotten super-popular in the last few years, which has led to a number of gimmicky Sudoku-themed items come out, few as ludicrous as this Sudoku watch.
I mean, the watch is nice-looking and all, but it only has a single level on its face. Once you solve it once, it loses its usefulness as a Sudoku watch. And for $1,000, I'd want it to have enough puzzles built in to last my entire life, not just the first 15 minutes I have it.
