Clock Answered

hello,
I recently acquired this clock (photos attached), after googling around, i think it is some type of network synced clock..
It has a green plastic cover with a transparent front side, the cover has no buttons at all ( it s not a radio clock).
the only input output are those 4 pins in the 4th photo.
I think it can be a good project,  maybe box it in wood, but i have no idea how to make it work.
can you help :)?
thanks

I will test it out a bit with a multimeter and small batteries to see how it ll work.Thanks

It does indeed look like a typical Quartz Xtal clock. If the OP can find a small crystal, that would the decider.

It looks similar to the one I had as a kid :)
From memory they work like this:
The "motor" is synced by the mains power frequency, this was an attempt to make these nice clocks more accurate.
On mine you could always hear a faint humming sound when it was plugged in.
I only had 2 buttons to set the time.
Press the first and the hours speed up, press the second and the minutes speed up - no reverse.
I guess with 4 buttons you might be able to set an alarm as well.

It should work when plugged in, if not you can check the mechanical part to make sure it moves free.
For this you will need to take the "motor" off as otherwise you might not be able to spin the wheels.
If you get it working again it would be a good idea to keep it original as they are going up in price for collectors.

I may have access to more than one of these.

Do you know by any chance where I could sell them?

Thanks.

this one doesn't have the buttons to regulate the time.

I think it works along with other deployed clocks all connected to a central controller that send pulses every minute to flip the cards.

I will be testing it out then building a standalone pulse generator to make it work properly.

It's an AM/FM clock radio. That's all. Those gear looking things are the tuning wheels for the radio. The copper winding is the AM loop. This is nothing from the future, from another planet, but from the 1980s or so. Ordinary, AM/FM clock radio that someone took the housing off of.

it s not a radio ,I took the housing off to take the photos.
the housing is just a plastic cover, transparent on the front side, no radio circuitry or buttons at all.
