The Minuteman One-Handed Watch ($164) is a cool take on the standard military watch. The watch takes a simple approach to telling time and although it may be a little imprecise, it is still a quick and easy way to tell the time within 5 minutes in just a single glance. It has twelve main marks that denote hours and smaller marks that denote 15 and 5 minute intervals. The single hand makes two full rotations each day. This watch is inexpensive and would make a great daily wear watch as well as a great conversation piece.
