1940's Valjoux 77 Chronograph Watch Movement Fijo Dial Runs & Stops For Parts

Vintage 1940's Swiss Made Valjoux 77 (17 jewel) manual wind up/down chronograph wristwatch movement with Fijo dial. It will run for a minute or two and stop then run again with a light twist. Not sure if anything is missing. I added a stock diagram of the Valjoux 77 movement in addition to the photos for comparison.
