The numbers you gave indicate to me that the movement is likely an A Schild caliber 1187/1194. A very common movement (hasn't been made for i'd say 50 years or so) for which parts will be readily available. However, if your diagnosis as to what is wrong with the watch is correct, it won't be simple for a newbie to repair. It will likely be easier and cheaper to locate a donor watch with a running movement, and perform a transplant. Another job not recommended for a newbie.
