Questions about electronic clocks
Hi all, I happened to win this Patek electronic clock from an auction, but could not get the clock running and I have a lot of questions about it.
After a bit of googling, this model L 4011, as engraved on the plate is supposed to be a radio signal clock, meaning it should be regulated with broadcasting radio signal rather than only quartz, but does it require an antenna? Cause after firing it up nothing seems to move, but when I touch the clock with my hands the red light on the bottom right flashes, which is kinda creepy but I think its because my body is transmitting some sort of frequency?
As seen in the picture I found out other than the power cable (white) theres another cable (Grey) with one end open, and the other end connected to the clock's module (remarked second) on the board. Does anyone know what should be connected to the open end?
And lastly, here are some supplementary pictures inside the shell.
I would really appreciate if any of you would share the knowledge of these clocks!
