P.W.C. swiss watch with 17 jewel FELSA 465 movement, ca.1950

This old P.W.C is most probably manufactured by Fabrique d'Horlogerie Perfecta SA / Simon Burger & Gressot. It has a sweep second movement by FELSA, cal. 465, with kind of sandwich construction. It has several cap jewels, 2 of them are at dial side. The movement was very dirty when I received the watch, and it had a bad smell, like gun oil. The mainspring was broken to three pieces. In spite the mainspring was broken, the watch ran few minutes after winding. I did not search correct mainspring, but I used a broken mainspring from ST96 movement. The ST96's mainspring had a broken hook, I heated the spring end to soften the steel and bent a new hook. I had to remove also some material from the hook as the new mainspring was 0.1mm wider than original, to make possible closing the barrel correctly. The watch runs nicely 40 hours with new mainspring (original power reserve is 38 hours).
Also the hands had a lot rust and the lume was dropped off. I removed the rust as well as I could, and applied cheap luminous paint to the hands. Also dial had some rust and the dial became much better by wiping it with baby wet wipe, without damaging the dial.
The watch seems to run rather nicely for its age, approximately +30 sec/24h and possibly it could be adjusted more accurate as there is no much variation in the accuracy.
