Guy: Thanks again for all of the help. I'll have to get to Radio Shack and then go at it with my voltmeter to see what I can accomplish. I think I'll give the zener diode a shot with a rheostat so that I can adjust it if need be to achieve the desired voltage because as you say, the clock only draws current when the spring is being wound. I will probably give it a shot later this week, but I'll keep you updated. I figure between some combination of a voltage step-down and tampering with the spring tension, I can get a clock that will hold the time (even when it is in the car). Steve
