I see a lot of rather nice Seiko(sha) slave clocks about, mostly scavenged from ships scrapped in the far east. By the time they get to the UK they have had their guts ripped out and a penny dreadful quartz movement  installed.

I have managed to find a Seiko slave movement to retro fit but does anyone know anything about how to drive them? How often they are pulsed and at what interval at what voltage or current?

Hi Don..I found a website advertising new Seiko marine clock systems and they were 24v alternate polarity, every 30 sec, pulses. Good to see the first post this year I think ! ?
