Sorry if this clock is a bit too modern for this forum, but I hope someone might be able to help! I recently bought this clock, an "Accuratick" made by "Kokusai Electric" in an Oxfam shop. It's very large (about 28cm on a side) and heavy: http://www.wessex.clara.net/Misc/AccuratickFront.jpg My eye was drawn by its smart, bold appearance, but I was very surprised when I turned it over and looked at the movement! http://www.wessex.clara.net/Misc/AccuratickBack.jpg Now to put it bluntly (bearing in mind any circuit that incorporates capacitors is beyond my understanding), what's going on here?! All I can think of is that this might be a "master" clock for a building full of "slave" clocks - is that right? There seem to be various circuit boards inside - in the centre, the movement - is that cylinder above it (top middle) the motor? (if so one of its wires has become disconnected). To the right, a power supply board with two transformers and some hefty capacitors. The mains lead from this, which should exit from the bottom of the clock, was snipped off by the Oxfam seller for safety reasons :-(. Bottom left, a board with four relays and lots more capacitors. What's that doing? Most mysterious is some kind of time-switch in the top left corner, with a knob that can be adjusted on the edge of the case, and a dial that runs from 5:30 to 16:00. Why those times?! Two of the wires leading to this appear to have been deliberately snipped at some point as can be seen in the picture. And just below the movement, bottom centre, is a solenoid (?) which seems to change the "spot" (visible on the face) from red to white. There are two sockets on the base of the clock; they seem to be designed to take simple metal "banana" plugs (if that's the right term, that is, not jack plugs or anything with more than one contact). Anyway, I haven't tried connecting it to the mains yet - thought I might wait for some sage advice first (google turns up nothing for "Accuratick" by the way, and nothing relevant for "Kokusai"). I would be interested to know what this clock is all about and whether I can/should run it as a standard mains clock. If it all sounds too complicated I might discard the current works and pop a battery movement on the back instead! Thanks for any help!
