If that's the case definitely do not change the mechanism, that is a real antique.I have the early version that can be started in either direction. It definitely does NOT start on it's own

My thought exactly.If that's the case definitely do not change the mechanism, that is a real antique.
I have discovered some more info on the clock. "INDUSTRIA ARGENTINA 5 amp 220 V" embossed on the plastic housing of the plug recepticle inside the cabinet. So, it was designed for a 50hz current. Hope this helps.Do you have a way of programming any MCU if I send you the file?
Otherwise I can send you a chip or the chip already mounted on a circuit board.
I also measured the resistance of the coil at 6.5 to 7 ohms. (analog gauge, so I can't be more accurate) The wire gauge of the coil is less than 34 AWG, but I don't know the exact size.I have discovered some more info on the clock.

It is an inductor, not a resistor.220V @ 7 ohms coil is 31 Amps,,,
So there must be some Transformer or other voltage limiter in it, can you measure the resistance of the mains lead with the clock connected.. you're still going to need a separate 50Hz oscillator.

You need to measure the current in the supply when it is running, even at 60Hz it will give an idea of the required supply. I suspect it will be very low.It is an inductor, not a resistor.
Thanks....it's amazing what you can find if you use the right words in a search. Now I need to decide if I want to spend almost $200 for it...ouch.Looks likes off-the-shelf units for running antique clocks on different mains might exist:

It will take me some time to get the measurements...need to borrow the meter from a friend, who is the middle of reconstructing his kitchen.You need to measure the current in the supply when it is running, even at 60Hz it will give an idea of the required supply. I suspect it will be very low.
Also here is another 50Hz oscillator circuit. https://www.elmelectronics.com/ic/elm446/
Well, it's a new year but I still haven't been able to determine the current draw of the coil for the clock motor. The scale of my friend's meter was too large to register anything. He claims to have another meter buried "somewhere", but there's no telling if he can find it or if it will be able to measure a current that is probably in milliamps. Also, he says he didn't have the equipment to build a shunt if we can find an appropriate meter. Comments? Suggestions? Prayers?You can use a crystal on the MCU instead of AC LINE frequency if you wish but the time-keeping ability will not be as good. I can put together a circuit for you if you wish but you will have to do some assembly.
We suspect that the coil takes very little current. More importantly we would like to know what is the lowest voltage at which the clock will still run.
Eventually, hope he could attend your case.Prayers?
