The 900 Abacus Watch($150) is I have ever seen most simple and clean watch. The point in time is presented by the fixed position of the ball. The ball rolls around inside face of the watch untill you reaches a horizontal position. Once you stop, the ball moves to the right point in time. Maybe it can not tell what accurate time, but who care, it really cool. It features stainless steel case, mineral or sapphire glass face, leather strap and water resistant to 30 meters.
