Vintage Chronographe Suisse Chronograph Watch for Parts / Repair Venus Mvt!

This watch is pretty worn out - the case especially - but perhaps is good for parts.
The balance staff seems intact and if you give watch a twist the balance wheel spins freely.  
Most all the parts seem to be there and intact but I am sure this needs a clean and oil to run as it should.
The stem is broken and the crown detached.
Base metal case parts are pitted and worn. The back cover is stainless steel - it has a slight depression.
The bezel is likewise stainless steel. The hands are all present. The dial with some signs of age and some soiling. 
One of the lugs seems a little bent on this watch.
Case diameter is about 36mm.

Sold as is for parts.
