Default Small slave clocks

Looking for some 6 inch or smaller diameter slave clocks and / or a panel mount dial. Don't mind what sort of movement (30 sec, 1 minute etc.).

Nobody's perfect. I'm a nobody. Therefore I'm perfect!

Default Re: Small slave clocks

The radio controlled clock movements have a 15 second drive for the minute/hour hands, as it is a bipolar drive it is easy to make a double pulse from a 30 second pulse, put a capacitor in series with the movement, loading the pulse with a resistor large enough to drop a volt or two.
