Here is a nice honest example of a vintage Citizen Cosmotron.  A watch series that I personally like because you can get some really bright colours, crazy dials and facet crystals.  All the things that ironically this one does not have!  I was drawn to this one because it has a nice chapter ring that draws your eye more into the dial which has a vertically grained pattern.   

The watch is all as it was new and its nice to see the original bracelet still with the watch as often these are long gone. 

Inside its powered by a 7802 electronic balance wheel movement from the early 70s, just as quartz were becoming a real thing. The movement is all mechanical other than it has a circuit board, coil and powered by a battery. There is no quartz though.  Circuit sends a pulse to the coil which is fitted between a double wheel balance wheel which has magnets on it. The pulse from the coil reacts with the magnet to spin the balance wheel which in turn turns a star shaped wheel that then powers the train.  Its absolutely amazing really as its powered backwards compared to a mainspring movement. 
These are beating at 36,000 beats per hour but weirdly the second hand is not as smooth as you would think.  It a trait of the movement in general rather than this specific watch. 
In essence you get a mechanical smooth tick watch that will always tell the right time.  I can see the logic in why they were invented.  
A nice genre of watch to have in your collection.  (also see my Seiko Elnix watches) 

I have checked this watch over and its running fine.  I have cleaned and oiled all pivots and balance wheel and greased the keyless works.  New crystal has been fitted along with caseback and crown gaskets.  Its all running well and ready for a new owner.
